The power of a study refers to the ability of a statistical test to correctly detect a difference or association in the population when it actually exists. Decreasing the overall alpha level from 0.10 to 0.05 would increase the power of the study.

The alpha level, also known as the significance level, is the probability of making a Type I error in a statistical test, which is rejecting the null hypothesis when it is actually true. By decreasing the alpha level, the statistical test becomes more stringent, and the likelihood of making a Type I error decreases.

For example, if the alpha level is 0.10, a statistically significant result would be achieved if the p-value (the probability of observing the test statistic under the null hypothesis) is less than or equal to 0.10. If the alpha level is decreased to 0.05, the p-value must now be less than or equal to 0.05 for the result to be considered statistically significant.

In general, decreasing the alpha level makes the test more conservative and increases the power of the study. However, this comes at the cost of increased likelihood of Type II error, which is failing to reject the null hypothesis when it is actually false.

Step-by-step explanation: désole.

Answer:

(x + 6)(x + 4)

Step-by-step explanation:

x² + 10x + 24

= x²+ 6x + 4x + 24=0

= x(x + 6)+4(x + 6)

= (x + 6)(x + 4)

Answer:

(x + 6)(x +4)

Step-by-step explanation:

x² + 10x + 24

    Sum = 10

Product = 24

Factors = 6 , 4        

{When we multiply 6 and 4, we get 24  & when we add 6 and 4, we get 10}

x² + 10x + 24 = x² + 6x + 4x + 24    {Rewrite the middle term using the factors}

The slope formula to calculate the slope of the ocean floor would be

[tex]slope = \frac{y}{x}[/tex].

What is slope?

The slope of a line characterizes its direction.

To find the slope of the ocean floor, we need to calculate the rise (change in depth) and the run (distance along the ocean floor) between the edge of the continental shelf and the beginning of the oceanic crust.

Let's call the depth of the water at the edge of the continental shelf "d1" and the depth of the water at the beginning of the oceanic crust "d2". Then, the rise is:

rise = d2 - d1

We don't have the actual values for d1 and d2, so let's call the rise "y" and the run "x". Then, the slope of the ocean floor is given by:

[tex]slope =\frac{rise}{run} \\\\slope = \frac{y}{x}[/tex]

Yes, when the length of the paper strip doubles, so will the number of dots on it.

Yes, when the length of the paper strip doubles, so will the number of dots on it. This is the case because the dots are uniformly spaced apart, and the total number of spaces between the dots doubles as the length of the strip does. As a result, to occupy the same number of spaces as the strip's length, the number of dots must also double. The same rule holds true for every paper strip of any length; increasing the strip's length will result in doubling the number of dots on it. The quantity of dots on the paper strip is therefore directly proportional to the length.

ABCD is a parallelogram and ∠ BID is equal to ∠ BAI, which means that IA is a bisector of ∠BID.

An angle's bisector divides the angle into two identical segments. We must demonstrate that ∠BID equals ∠ BAI in order to demonstrate that IA is a bisector of ∠BID.

Since ABCD is a parallelogram, we have:

AB || CD, which means that ∠ABD is equal to ∠ADC.

BC || AD, which means that ∠ ABC is equal to ∠ DAC.

Adding these equal angles, we have:

∠ABD + ∠ ABC = ∠ ADC + ∠ DAC

∠BDA = ∠CDA

Also, since BM = DN, we have:

∠DBM = ∠ DNM (by vertical angles)

Adding these equal angles, we have:

∠ BDA + ∠ DBM = ∠CDA + ∠ DNM

∠ BID = ∠ BAI

Therefore, we have shown that ∠ BID is equal to ∠BAI, which means that IA is a bisector of ∠BID.

The coordinates of point P that lies along the directed line segment from M to N and partitions the deferment in the ratio 3 to 2 is (6/ 5 , 0).

The line segment is divided into two pieces by a point, which may or may not be equal. If we know the coordinates of the point, we may calculate the ratio by which the supplied line segment is divided. Additionally, if we are aware of the ratio that the line segment connecting two places has produced, we can locate the point of division. The two can be accomplished using a section formula from coordinate geometry.

The coordinates of the points on the line are:

M = (-3, -3)

N = (4, 2)

m= 3

n = 2

Using the section formula we have:

M(x, y) = (mx2 + nx1 / m+n , my2 + ny1 /m + n)

M(x, y) = ((3)(4) + (2)(-3)) / (3 + 2) , (3)(2) + (2)(-3) / (3 + 2))

M (x, y) = (12 - 6 / 5 , 6. -6 / 5)

Answer:

D 588 miles

Step-by-step explanation:

We know

Leo is training for a marathon later this summer. He has run 42 miles over the last 3 days.

42 divided by 3 = 14 miles per day

So, he runs at a rate of 14 miles per day.

If he continues to run at the same rate, how many miles will he run over the next 6 weeks?

1 week = 7 days

1 week = 14 x 7 = 98 miles

6 weeks = 98 x 6 = 588 miles

So, he will run 588 miles over the next 6 weeks.

The appropriate test to see if neck size and number of teeth have a linear relationship in 18 randomly selected puppies is the t-test for slope of regression line.

A regression line is a line that best fits the data by minimizing the sum of the squared differences between the observed and predicted values. A t-test for slope of regression line tests the null hypothesis that the slope of the regression line is equal to zero, which would indicate that there is no linear relationship between the variables.

In this case, neck size and number of teeth are two continuous variables and we want to test if there is a linear relationship between them. A t-test for slope of regression line would provide information on the significance of the relationship and the direction of the relationship (positive or negative).

It is important to note that the test conditions such as independence, normality, and homoscedasticity must be met before conducting the test. If these conditions are not met, the results of the test may be biased and should be interpreted with caution.

The air conditioner is being sold for $673.20. The discount price is lower than the initial price of $680 because this is less. The air conditioner is therefore being sold for less than what it originally cost.

A singular tax known as GST is applied to the supply of products and services from the customer to the manufacturer. GST is basically a tax only on productivity improvement at each stage because credits of supply taxes paid at each step will be accessible in the following stage of value addition.

The first step is to calculate the GST that is added to the original price of the air conditioner:

GST = 10% of $680 = 0.1 x $680 = $68

So the total cost of the air conditioner including GST is:

Total cost = $680 + $68 = $748

Now, the air conditioner is sold at a 10% discount. To find the sale price, we need to subtract 10% of the total cost from the total cost:

Sale price = Total cost - 10% of Total cost

= $748 - 0.1 x $748

= $748 - $74.80

The distance between the golf balls is determined to be 14 feet.

Let's call the distance between the two golf balls "d".

Using the law of cosines, we can find the value of d by using the angles and the two distances to the hole:

d² = 8² + 13² - 2 * 8 * 13 * cos(64)

d² = 64 + 169 - 104 * cos(64)

d² = 233 - 104 * cos(64)

Next, we'll use a calculator to find the value of cos(64):

cos(64) = 0.37

So,

d² = 233 - 104 * 0.37 = 233 - 38.48

d² = 194.52

Finally, we'll take the square root of both sides to find the value of d:

Negative numbers are obviously smaller than positive numbers, hence, we have -4/9 and -3/2.

-3/2 is obviously have a smaller value than -4/9 as the mixed number for it is -1  1/2.    [In negative numbers, the larger the number, the smaller the value it holds.]

[tex]0.7= \frac{7}{10}[/tex]

We can turn the denominator of 2/11 and 7/10 to the same number, 110.

[tex]\frac{2}{11} = \frac{20}{110}[/tex]

[tex]\frac{7}{10} = \frac{77}{110}[/tex]
