4. [-/1 Points] DETAILS UHSTAT4 11.E.041. MY NOTES PRACTICE ANOTHER Suppose a randomly selected sample of n = 52 men has a mean foot length of x = 26.8 cm, and the standard deviation of the sample is 5 cm. Calculate an approximate 95% confidence interval for the mean foot length of men. (Round the answers to one decimal place.) cm 5. [-/1 Points] DETAILS UHSTAT1 11.E.042. MY NOTES PRACTICE ANOTHER In the study, n = 51 men were put on a diet. The men who dieted lost an average of 6.8 kg, with a standard deviation of 3.5 kg. (a) Compute the standard error of the mean for the men who dieted. (Round the answer to two decimal places.) (b) Compute an approximate 95% confidence interval for the mean weight loss for the men who dieted. (Round your answer to the nearest hundredth.) An approximate 95% confidence interval is
