A medical college dean read that the average number of applications a potential medical school student sends is 7.6. She thinks that the mean differs from 7.6. So she selects a random sample of 26 applicants and asks each how many medical schools they applied to. The mean of the sample is 7.9. The population standard deviation is 2.4. Test her claim at =α0.05. Assume that the variable is normally distributed. Use the P-value method with tables. State the hypotheses and identify the claim. This Hypothesis is a (one tailed or two tailed test)
