QUESTION 20
A poll by the National Sleep Foundation found that college students on average sleep about 7 hours per night. A sample of 169 college students yielded an average of 6.88 hours, with a standard deviation of 0.94 hours. Assuming that this is a random sample representative of all college students, a hypothesis test at significance level 0.05 was conducted to evaluate if college students on average sleep less than 7 hours per night. The p-value for this hypothesis test is 0.0485. Which of the following is the correct interpretation of this p-value
A. | The probability that students on average sleep less than 7 hours per night. | |
B. | The probability that students on average sleep less than 7 hours per night, if in fact a random sample of 169 students yields an average of 6.88 hours or less | |
C. | The probability that students on average sleep less than 7 hours per night, if in fact a random sample of 169 students yields an average of 6.88 hours or less | |
D. | The probability that a random sample of 169 students on average sleep 6.88 hours or less per night, if in fact students on average sleep 7 hours per night. |
