The diameter of small nerf balls manufactured at a factory in china is expected to be approximately normally distributed with a mean of 5.2 inches and a standard deviation of .08 inches. suppose a random sample of 20 balls is selected. calculate the standard deviation of the sampling distribution of the sample mean.

0.018

Step-by-step explanation:

The standard deviation of the sampling distribution of the sample mean is given by :-

Given : and

Then, the standard deviation of the sampling distribution of the sample mean :

Hence, the standard deviation of the sampling distribution of the sample mean = 0.018

answer: a numerical coefficient is a constant multiplier of the variables in a term. in the term -5x2y, the numerical coefficient is -5. in the expression ax2 + bx + c, the numerical coefficient of the x2 term is "a" and the numerical coefficient of the x term is "b".
