Question

Assume that the population of heights of male college students is approximately normally distributed with mean m of 70.63 inches and standard deviation s of 6.47 inches. A random sample of 88 heights is obtained. Show all work.
(A) Find the mean and standard error of the distribution

Answer 1

Standard error is a measure of a reasonable difference between a sample mean and the parent mean.
In this case the standard error for a random sample of 88 heights is:
\[\frac{\sigma}{\sqrt{n}}=\frac{6.47}{\sqrt{88}}=?inches\]

Answer 2

already finsh this problem thanks
