If a person is randomly sampled from this population, what is the probability that this person's BP is between 108 mm Hg and 114 mm Hg? 2. By Hand: Data on men's serum cholesterol levels (in mg/dL) were analyzed to determine the SEM. Here's the output: Frequencies Statistics Serum_level N Valid 30 Missing Mean 264.43 Std. Error of Mean 13.759 Median 250.50 Std. Deviation 75.361 Using the information provided in the output, calculate the 95% confidence interval and interpret the results. Now calculate the 99% confidence interval and interpret the results. Why is the 99% confidence interval calculated above wider than the 95% confidence interval? 0= 1 O = Dashboard Calendar To Do Notifications Inbox
