A realty company looks at a recent sample of houses that have sold. On testing the null hypothesis that 56% of the houses take more than three months to sell against the hypothesis that more than 56% of the houses take more than three months to sell against the hypothesis that more than .014. Which answer is appropriate?
A. There is a 1.4% chance the null hypothesis is correct.
B. There is a 1.4% chance that 56% of the houses take more than 3 months to sell.
C. If 56% of the houses take more than three months to sell, there is 1.4% chance that a random sample proportion would be as high as or higher than the one they obtained.
D. There is a 96.8% chance that 56% of the houses take more than 3 months to sell.
Answer)
P-value is the probability of obtaining the results as high or higher than the one obtained if null hypothesis is true
Here p-value is 0.014 that is 1.4%
So answer is
C. If 56% of the houses take more than three months to sell, there is 1.4% chance that a random sample proportion would be as high as or higher than the one they obtained.

(7 points) Suppose a recent random sample of employees nationwide that have a 401(k) retirement plan found that 20% of them had borrowed against it in the last year. A local company is interested in assessing whether this proportion adequately describes the borrowing behavior of their employees. They take a random sample of 150 employees and find that 17 had borrowed from their plan. Conduct a hypothesis test to investigate whether the borrowing rate at this company is less than...

4/15/2019 Prieto 13. According to a certain government agency for a large country, the proportion of fatal traffic accidents in the which the driver had a positive blood alcohol concentration (BAC) is 0.39.

Question 2 of 3 (1 point) | Question Attempt: 1 of Unlimited 2 3 A recent study at a local college claimed that the proportion, p, of students who commute more than fifteen miles to school is no more than 15%. If a random sample of 265 students at this college is selected, and it is found that 53 commute more than fifteen miles to school, can we reject the college's calm at the 0.05 level of significance? Perform a...
Would you favor spending more federal tax money on the arts? Of a random sample of n = 93 politically conservative voters, 1 = 17 responded yes. Another random sample of n2 = 78 politically moderate voters showed that r2 - 22 responded yes. Does this information indicate that the population proportion of conservative voters inclined to spend more federal tax money on funding the arts is less than the proportion of moderate voters so inclined? Use a = 0.05....
ESAND ABUSES 1 Uses Hypothesis Testing Hypothesis testing is important in many different fields because it gives a scientific procedure for assessing the validity of a claim about a population. Some of the concepts in hypothesis testing are intuitive, but some are not. For instance, the American Journal of Clinical Nutrition suggests that eating dark chocolate can help prevent heart disease. A random sample of healthy volunteers were assigned to eat 3.5 ounces of dark chocolate each day for 15...
1. Hypothesis Testing - Setup: Suppose you want to test the claim that the mean volume in all 12-ounce cans of Fizzy Pop soda is equal to 12 ounces. In a sample of 120 cans, you find the sample mean is 12.2 ounces. (a) What is the claim? μ < 12 μ > 12 μ = 12 μ = 12.2 (b) What does μ represent? the proportion of all cans with a volume = 12 ounces the mean volume of...
