Question 5 1 pts Suppose that the number of credit hours a student takes follows a normal distribution with a mean of 15 credit hours and a standard deviation of 2 credit hours. A normal course load is between 12 and 18 hours. What proportion of students do not have a normal course load? between 0.5 and 0.9 O between 0.05 and 0.49 greater than 0.9 O less than 0.05 Question 6 1 pts A hypothesis test is testing the following hypotheses: Ho: u = 10; H. + 10. Data were collected from 100 subjects, and the sample mean was T = 13. The p-value found was 0.02. What does this p-value mean? That if the true population mean really is 10, the probability of observing a mean of 13 or more, or a mean of 7 or less, in a sample of 100 subjects, is 0.02. That if the true population mean really is 13, the probability of observing a mean of 13 or more, or 7 or less, in a sample of 100 subjects, is 0.02. O That if the true population mean really is different from 10, the probability of observing a mean of 13 or more in a sample of 100 subjects, is 0.02. That if the true population mean really is 13, the probability of observing a mean of 13 or more in a sample of 100 subjects, is 0.02.
