Among various ethnic groups, the standard deviation of heights is known to be approximately three inches. We wish to construct a 95% confidence interval for the mean height of male Swedes. Forty-eight male Swedes are surveyed. The sample mean is 73 inches. Round answers to 3 decimal places. a. Find the following: i. = ii. o = iii. n = b. Construct a 95% confidence interval for the population mean height of male Swedes. i. State the confidence interval. ii. Calculate the error bound. c. What will happen to the size of the confidence interval if 1,000 male Swedes are surveyed instead of 48? The confidence interval will
