The statistical test that a researcher could use to test the null hypothesis that the mean body temperature of residents in a nursing home is 98.6°F is a one-sample t-test.
What is a statistical test?A statistical test is a method that enables the comparison of the collected data with the assumed distribution of the data. A statistical test aids in determining if the outcomes of the experiment or research are caused by the treatment or if they are due to the random variation in the data.
A null hypothesis is a type of hypothesis that predicts the absence of a relationship between variables or groups. The null hypothesis claims that no difference exists between two variables or groups, and that any observed differences are due to chance.
Alternative hypotheses are used to reject null hypotheses, as they predict the presence of a relationship between variables or groups.
The significance level, which is the probability of committing a Type I error, is often used to set the null hypothesis. The statistical test that a researcher could use to test the null hypothesis that the mean body temperature of residents in a nursing home is 98.6°F is a one-sample t-test.
The t-test will aid in determining if the difference between the mean body temperature of residents in the nursing home and 98.6°F is statistically significant.

The equation to show the relationship between x and y is y = 0.08x, where y is the amount of sales tax in dollars for the item and x is the cost of the item in dollars before tax.
What is tax?Tax is a compulsory financial charge or some other type of levy imposed upon a taxpayer by a governmental organization in order to fund various public expenditures. A failure to pay, along with evasion of or resistance to taxation, is punishable by law. Taxes consist of direct or indirect taxes and may be paid in money or as its labour equivalent. Most countries have a tax system in place to pay for public, common or agreed national needs and government functions. Some levy a flat percentage rate of taxation on personal annual income, but most scale taxes based on annual income amounts.
This equation reflects the fact that the amount of sales tax for an item is 8% of its cost before tax.

Describe the center of the dot plot. What single dot would best represent the data?
The center, 6, is less frequent than the neighbor values, but the single dot that best represents the data still is 6.
What can we say about the center?Each point on the dot plot over each number represents the amount of times that we have that value in the data set.
Here the center is 6, and we can see that we have only one point in 6, while in the neighbors we can see more points, then we can see that the center is less populated than the neighbor values.
Now, what single dot would best represent the data?
To answer that we need to get the mean of the data set,
Counting the values in the graph, and dividing by the number of points, we have:
mean = (3 + 4 + 4 + 5 + 5 + 6 + 7 + 7 + 8 + 8+ 8+ 9)/12 = 6.16

Mrs. Banks has enough fruit to make the 44 qt of jelly she wants, but she will have 4 lb of leftover fruit.
Here we have to use the arithmetic operations. First, we need to convert the total quantity of jelly to gallons since we have the amount of fruit needed per gallon. One gallon is equal to 4 quarts, so 44 quarts is equal to 11 gallons.
Next, we can calculate how much fruit is needed for 11 gallons of jelly by multiplying the amount of fruit needed per gallon by the number of gallons
11 gallons x 6 lb of fruit per gallon = 66 lb of fruit needed
Since Mrs. Banks only has 70 lb of fruit, she has enough to make the 44 qt of jelly she wants, but she will have 4 lb of leftover fruit:

find three positive integers x, y, and z that satisfy the given conditions. the product is 1 and the sum of the squares is a minimum.
The minimum value of the sum of squares is 3 when all three numbers are equal to 1.
Given the condition that the product of three positive integers x, y, and z is 1 and the sum of the squares is a minimum, we have to find out the three numbers that satisfy this condition.The three numbers that satisfy the condition arex = 1, y = 1, and z = 1 because the product of any number and 1 is the number itself, and the sum of the squares of all the numbers is also 1. Thus, the answer is (1,1,1).It can be proved mathematically that the answer (1, 1, 1) is correct:Product of three positive integers is 1 if and only if all three numbers are equal to 1.If three positive integers a, b, and c have a fixed sum, then the sum of the squares of two of the integers is the minimum when they are equal to each other and their sum is equal to half of the fixed sum.Thus, the sum of the squares of the three numbers is 1 + 1 + 1 = 3, and the minimum value of the sum of squares is 3 when all three numbers are equal to 1.

By combinations, we get that there are 20,020 possible 6-topping pizzas.
Given that a pizza parlor offers a choice of 16 different toppings, we need to find the number of 6-topping pizzas that are possible. No double-orders of toppings are allowed. What is the number of 6-topping pizzas that are possible?
The formula for combinations is as follows:
ncr = (n!)/(r! * (n - r)!) where n = 16 (total number of toppings available)
r = 6 (number of toppings required for a pizza)
ncr = (16!)/(6! * (16 - 6)!)
⇒ ncr = (16!)/(6! * 10!)
⇒ ncr = (16 * 15 * 14 * 13 * 12 * 11)/(6 * 5 * 4 * 3 * 2 * 1)
⇒ ncr = (16 * 3 * 5 * 7 * 13 * 11)/(3 * 2 * 2)
⇒ ncr = 20,021
In this situation, the order of the toppings does not matter. Therefore, we cannot have a repeat of the same toppings, as mentioned. Hence the answer to the question is no. Thus, there are 20,020 possible 6-topping pizzas.

Estimate the probability that at least 60 color-blind men are in the sample. Use a TI-83, TI-83 plus, or TI-84 calculator to find the probability. Round your answer to four decimal places. Provide your answer below:
Solution:
Let the probability of the man having the trait of color blindness be p. Then, p = 0.09, and the sample size is n = 700.Mean and Variance of Binomial Distribution are:μ = np and σ² = np(1 − p)Here, p = 0.09, n = 700μ = np = 700(0.09) = 63Andσ² = np(1-p) = 700(0.09)(0.91) = 5.679Now we need to find the probability that at least 60 color-blind men are in the sample.i.e., P(X≥60)By using the Central Limit Theorem, we can approximate this binomial distribution as a normal distribution with mean μ = 63 and variance σ² = 5.679.P(X≥60) can be calculated using the following formula:P(Z≥((60-63)/√(5.679))) = P(Z≥(-1.684))Now we need to look at the z-table or use the calculator to find the value of P(Z≥(-1.684))P(Z≥(-1.684)) = 0.9537 (rounded to four decimal places)Therefore, the estimated probability is 0.9537 (rounded to four decimal places).Hence, the answer is 0.9537.

Explain about the subtraction of numbers?Subtraction is the activity or procedure of determining the variance between two amounts or numbers. The phrase "taking away one numeral from another" is also used to describe the act of subtracting one number from another. Making payments, sending cash to pals, and many more situations call for the use of subtraction.
Several words found in a subtraction statement are frequently employed when subtracting two numbers:
A minuend is really the number that is deducted in order to arrive at the other number.Subtrahend: The amount that needs to be deducted from the minuend is known as a subtrahend.Difference: A difference is the outcome obtained by deducting a subtractor from a minimum.In the given question:
Money stolen $100.
Worth of goods purchased = $70.
Returned money by shopkeeper = $30.
Total amount = $100 + $70 + $30.
$100 is again payed by the shopkeeper.
Thus, subtracting:
Amount = $200 - $100
Thus,
Loss = $100.

The values of unknown angles in the given figures are:
(a) a° = 117°, b° = 117°, c° = 63°, d° = 78°
(b) e° = 31°, f° = 66°
(c) g° = 69°, h° = 83°
(d) i° = 45°, j° = 60°
What are angles?Angles are formed when two rays join at a common point. The common point can also be called as a node or vertex, and the two rays are called angle arms. Angles are usually represented by the "∠" symbol. The word angle is derived from the Latin "Angulus". Learn more about lines and angles here. Angle types are based on angle values in degrees. You can also express angles in radians, or pi (π). 180° is equivalent to pi radians.
For the given figures:
a° = 117° [ Vertically opposite angles]
b° = 117° [Corresponding angle]
c° = 180° - 117° [Linear pair]
c° = 63°
d° = 78° [Corresponding angle]
e° = 31° [Alternate interior angles]
f° = 66° [Alternate interior angles]
g° = 69° [Corresponding angle]
h° = 83° [Alternate interior angles]
j° = 60° [Alternate interior angles]
i° = 180 - (75 + 60) [Angle sum property of triangle]

If PQRS and TSUV are congruent parallelograms, which angle in parallelograms TSUV is congruent to ∠PQR?
The PQRS and TSUV are congruent parallelograms, they have the same shape and size. angle PQR is congruent to angle TSU, since they are opposite angles in parallelograms PQRS and TSUV, respectively. so angle TSU in parallelogram TSUV is congruent to angle PQR.
What distinguishes a parallelogram?The following are a parallelogram's characteristics:
The two opposing sides are level and parallel.
The opposing angles line up evenly.
The following or adjacent angles are extra.
Every angle will be at a right angle if even one of the other angles is.
PQRS and TSUV are congruent parallelograms, which denotes that their dimensions are the same. The parallelograms' corresponding angles are therefore equal.
Angle PQR is an interior angle in the parallelogram PQRS that is opposite to the adjacent angle PQS, whereas angle UTS is an internal angle in the parallelogram TSUV that is opposite to the adjacent angle TSV.
We can infer that angle PQR and angle UTS are related angles and are hence congruent because PQRS and TSUV are congruent.
