You measure the heights of a random sample of 400 high school sophomore males in a Midwestern state. The sample mean is 66.2 inches. Suppose that the heights of the population of all high school Sophomore males follow a normal distribution with unknown mean and standard deviation ( = 4.1 inches. You compute a 95% confidence interval for 1. Suppose you had measured the heights of a random sample of 100 sophomore males rather than 400. Which of the following statements is true? A) The margin of error for our 95% confidence interval would decrease. B) would decrease. C) The margin of error for our 95% confidence interval would increase. D) The margin of error for our 95% confidence interval would stay the same, because the level of confidence has not changed
