Question

According to the National Health Survey, the weights of individuals are normally distributed. Men have an average weight of 172 pounds, with a standard deviation of 29 pounds. Suppose we select 64 male students from Math 203. Find the sample standard deviation for this sample. Give your answer to three decimal points.

Answer 1

3.625

Explanation:

The formula for sample standard deviation = Population standard deviation/√n

Where n = number of random samples

Population standard deviation = 29 pounds

n = 64 male students

Sample standard deviation = 29/√64

= 29/8

= 3.625

Therefore, the Sample standard deviation = 3.625
