kropot72 · Answer

It is necessary to chose appropriate values of the random variable X, the population mean and the standard deviation that will give the required values of z-score.
Do you know the formula to calculate a z-score?

andijo76 · Answer

well we are suppose to do this  

Calculate the z-scores for each subject for two variables—hours worked per week and satisfaction with income.

Compute the mean and the standard deviation for the population for the two variables.
Starting with the z-score formula, show all the steps of the calculations for the z-scores for each variable.

On the basis of your calculations, describe for each subject how you would interpret any potential relationships between the number of hours worked per week and the subject's satisfaction with his or her income.

Starting with the formula and substituting values for each variable, provide all the steps of the calculations to arrive at a z-score of +1.4. Show all steps of the calculations to arrive at a z-score of −2.2.

Did you calculate the mean and the standard deviation for each set of data?

andijo76 · Answer

the first set i have to do the second set

andijo76 · Answer

okay i have the mean and the standard deviation( population )for both sets

andijo76 · Answer

Mean	28.66667 (hours)
	3.66667 (income)
SD(P)	19.821425 (hours)
	1.154701 (income)
