If it is assumed that the heights of men are normally distributed with a standard deviation of 2.5 inches, how large a sample sh

Volgvan

Answer:

30 men

Step-by-step explanation:

In order to be sure that the sample mean does differ from the population mean by more than 0.90, the sample size (n) that should be used is given by:

$0.90 < Z\frac{s}{\sqrt{n}}$

Where 'Z' , for a 95% probability is 1.960, 's' is the standard deviation of 2.5 inches:

$0.90 > 1.960\frac{2.5}{\sqrt{n}}\\n >(\frac{1.960*2.5}{0.9})^2\\n>29.64$

Rounding up to the nearest whole number, the sample size should be at least 30 men.
