(c) The height of students in a college are normally disturbed with \( \mu=60^{\prime \prime} \) and \( \sigma^{2}=100^{\prime \prime} .500 \) student are studying in this college. Find the number of students where height is (i) At least 24" (ii) Between 40" and 72" (iii) More than \( 65^{\prime \prime} \) (iv) Less than \( 30^{\prime \prime} \) Find also mean deviation, quartile deviation and median.

Assume that the heights of 3000 male students at a university are normally distributed with mean 68.0 inches and a standard deviation of 3.0 inches. If 80 samples consisting of 25 students each are obtained, what would be the mean and standard deviation of the resulting sample of means if sampling were done (a) with replacement, (b) without replacement?

The heights of 1000 students are approximately normally distributed with a mean of 174.5 centimeters and a standard deviation of 6.9 centimeters. If 200 random samples of size 25 are drawn from this population and the means recorded to the nearest tenth of a centimeter, determine (a) the mean and standard deviation of the sampling distribution of $\bar{X}$; (b) the number of sample means that fall between 172.5 and 175.8 centimeters inclusive; (c) the number of sample means falling below 172.0 centimeters.
