1. Researchers want to find out that the average heart rate of male college students is greater than 75. Assume a random sample of 80 male college students were taken for the study. The sample mean was 79.8 and the population standard deviation is known to be 49.85. Carry out the hypothesis test. (a) State the appropriate hypothesis (b) What is the standardized test statistics? (c) What is the null đistribution of the TS? (d) What is the rejection region for the test? (e) Is the test significant at a = 0.05? (f) What is the p-value?
