Question
A police officer claims that the proportion of drivers wearing a seat belt in a certain area is less than 40%.
To test this claim, the officer collects a random sample of 80 drivers and monitors if the driver was wearing a seat belt.
From this sample of 80 drivers, the police offers observes that 34 were wearing seat belts.
Assume the conditions needed to conduct a one sample proportion test are satisfied.
The setup for the null and alternative hypothesis is as follows:
H : p = 0.40; H, :p < 0.40, which is a left-tailed test.
Compute the test statistic and p-value for this Hypothesis test using Excel and round your answers to 3 decimal places.
Answer:
0.456
0.324
Explanation:
The null and alternative hypothesis :
H0 : p = 0.40; HA :p < 0.40
Test statistic :
(Ph - P) / sqrt[(p*(1-p))/n]
Ph = X / n
X = 34 ; n = sample size = 80
Ph = 34 / 80 = 0.425
(0.425 - 0.4) / sqrt[(0.4(0.6)) / 80]
0.025 / sqrt(0.003)
0.025 / 0.0547722
Test statistic = 0.4564359
Test statistic = 0.456
Using the P-value from Zscore calculator :
Significance level of 95% ; one tailed
Z statistic value = 0.456
P value = 0.324195
= 0.324 ( 3 decimal places)
Answer:
test statistic=0.456 p value=0.676

g) In a college 60% of students come from rural areas and 40% come from urban areas. On the
average 30% of students from rural areas study science and 50% of the students from urban areas study
science. A student is selected at random and is found to be a student of science. Find the probability
that he comes from a rural area.
Answer:
100-(50+30)=100-80=20%
Explanation:
20% is the answer
hope it helps you
please mark me as brainlist
The probability that he comes from a rural area is to be calculated as
100-(50+30)=100-80=20%. So, the probability that he comes from a rural area. So, the probability is 20%.
What is probability?Probability deals with the likelihood of an event or phenomena occurring and is quantified as a number between 0 and 1 inclusive, where 0 indicates an impossible chance of occurrence and 1 denotes the certain outcome of an event. Joint probability refers to a statistical measure that determines the probability of two events occurring together and at the same point in time.
Joint probability is the probability of event Y occurring at the same time that event X occurs. Hence, joint probability is a measure of two events happening at the same time and can only be applied to situations where more than one observation can occur at the same time. Mathematically, it is given by P (A and B) = P(A) * P(B) As in the given situation, the probability estimated is the probability to two events that iPhone is defective and it is manufactured by company A occurring at the same time, it is a joint probability.
Therefore, Probability deals with the likelihood of an event or phenomena occurring and is quantified as a number between 0 and 1 inclusive.

A store clerk is paid $10.75/ hour and a store assistant manager is paid $16.25/ hour. How long would it take the store managerto make $500 or more than the store clerk? Round to the nearest hour. Show all work.
It will take approximately 91 hours for the store manager to make $500 or more than the store clerk.
If the store clerk is paid $10.75/ hour and the store assistant manager is paid $16.25/ hour, the difference in their pay per hour will be expressed as:
The difference in the amount earned per hour = 16.25 - 10.75
The difference in the amount earned per hour = $5.5
This means that the store assistant manager will collect $5.5 more than the store clerk in one hour. This can be expressed as:
$5.5 = 1 hour
To determine how long it will take the store manager to make $500 or more than the store clerk, we can write:
$500 = x
Divide both expressions:
[tex]\dfrac{5.5}{500} =\dfrac{1}{x} \\Cross \ multiply\\5.5x = 500 \times 1\\5.5x = 500\\x=\frac{500}{5.5}\\x= 90.9 \ hours[/tex]
This means that it will take approximately 91 hours for the store manager to make $500 or more than the store clerk.

Answer of #1
5 Cows and 16 Ducks
Explanation:
4x + 2(21-x) = 52
4x + 42 - 2x = 52
2x + 42 = 52
- 42 - 42
2x = 10
x = 5 Number of cows
21 - 5 = 16 ducks.
Checking: The 5 cows have 5 x 4 = 20 legs. The 16 ducks have 16 x 2 = 32 legs.
32 + 20 = 52
