5. We test if the population mean body temperature of AUM is equal to 97° F. We collected a sample with the sample mean 98° F among n = 9 this year. Assume that AUM body temperatures are normally distributed with o = 1.5° F. Perform the test with a significance level a = 0.05. %3D (a) State the null and alternative hypothesis. (b) Find the critical value for the test and conclude. (c) Find the p-value and conclude. (d) Find a 95% confidence interval and conclude.
