Problema Solution
Assume that the population of heights of female college students is approximately normally distributed with mean m of 64.37 inches and standard deviation s of 6.26 inches. A random sample of 74 heights is obtained. Show all work.
(A) Find the mean and standard error of the distribution
(B) Find
Answer provided by our tutors
The Standard Error or otherwise SE of the mean is calculated by taking the Standard Deviation and dividing by the square root of the number of samples, 74.
that would be 6.26/V74 = 0.69
The mean is just adding all heights and dividing them by the amount of students
