Among various ethnic groups, the standard deviation of heights is known to beapproximately three inches. Forty-eight male Swedes are surveyed. The sample mean is71 inches. A 96% confidence interval for the population mean heiglht of male Swedes is:O (71.167,72.833)O (70.151,71.849)(70.167,71.833)(70.238,71.762)
