Let x denote daily work hours. suppose that for the sample of workers you have, the average daily work hours are 8 hours, with a standard deviation of 5. suppose now let z denote weekly work hours, find the mean and standard deviation for z (assuming everyone works 5 days per week in your sample).

The mean for Z is 40.

The standard deviation for Z is 25.                      

Step-by-step explanation:

We are given the following in the question:

X:  daily work hours.

The average daily work hours are 8 hours, with a standard deviation of 5.

Z denote weekly work hours.

We have to find the mean and standard deviation for Z.

The mean for Z is 40.

We use the property:

Thus, the standard deviation for Z is 25.

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
