Masters, the mean number of tires replaced is M = 3, 14, with a standard deviation of0= 1.24. Suppose that we will take a random Sample of n=7 tire replacement orders. (Each order gives the number of tires replaced.) Let represent the sample mean of the 7 tire replacement orders.
Consider the sampling distribution of the sample mean X.
Write your answers with two decimal
places, rounding if needed.
A) Find M (the mean of the sampling distribution
of the sample mean.
ux=
B.) Find (the standard deviation of the sampling
distribution of the sample mean
