Question

It is widely reported that high school students spend an average of 7 hours per week working on homework. Miss Bonnar, a high school English teacher, questions this report. She believes the students at her high school spend more than 7 hours per week working on homework. She surveys a random sample of 95 students and plans to use the resulting data to conduct a hypothesis test. Suppose the p-value from this hypothesis test is 0.01. Which of the following is a correct interpretation of this p-value?
A. Approximately 1% of the students in the sample spend more than 7 hours per week working on homework.
B. The probability of obtaining a result at least as extreme as the one observed, if the null hypothesis is true, is 0.01.
C. The probability that the null hypothesis is true is 0.01.
D. The probability that the null hypothesis is false is 0.01.
E. If we assume to begin with that the null hypothesis is false, there is only a 1% chance we will reject that null hypothesis.

Answer:

B. The probability of obtaining a result at least as extreme as the one observed, if the null hypothesis is true, is 0.01.

Step-by-step explanation:

The answer choice B is in fact the definition of p-value.
