Math 310-Assignment 3- Question * Among various ethnic groups, we want to construct a 95% confidence interval for the mean height of male Swedes. 25 males Swedes are surveyed. The sample mean is 71 inches. The sample standard deviation is 2.8 inches. Assuming normality of height of male Swedes, the 95% confidence interval for the mean height is: O [69.8441, 72.1558] [68.111, 72.732] [68.764, 72.866] O [69.001, 72.426] Question
