The heights of 1000 students are approximately normally distributed with a mean of 174.6 centimeters and a standard deviation of 7.5 centimeters. Suppose 400 random samples of size 25 are drawn from this population and the means recorded to the nearest tenth of a centimeter. Complete parts (a) through (c) below.
