Suppose that the average weekly earnings for employees in general automotive repair shops is $450, and that the standard deviation for the weekly earnings for such employees is $50. a sample of 100 such employees is selected at random. find the standard deviation of the sampling distribution of the means of average weekly earnings for samples of size 100

 5

Step-by-step explanation:

We know that the standard deviation of the sampling distribution of the means is given by :_

Given : The average weekly earnings for employees in general automotive repair shops is.

The standard deviation for the weekly earnings for such employees =

Now, the standard deviation of the sampling distribution of the means of average weekly earnings for samples of size:-

Hence, the standard deviation of the sampling distribution of the means of average weekly earnings for samples of size 100 = 5

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
