Medical School Applications A medical college dean read that the average number of applications a potential medical school student sends is 7.8. She thinks that the mean is different. So she selects a random sample of 38 applicants and asks each how many medical schools they applied to. The mean of the sample is 8.2. The population standard deviation is 2.8. Test her claim at a = 0.05. Assume that the variable is normally distributed. Use the P-value method with a graphing calculator. Part: 0 / 4 Part 1 of 4 (a) State the hypotheses and identify the claim. Ho: H = 38 claim 0 0=0 K H1 : H
