Suppose a business records the following values each day the total number of customers that day (X) Revenue for that day (Y)

A summary of X and Y in the previous days is

mean of X: 600 Standard deviation of X : 10

Mean of Y: $5000 , Standard deviation of Y: 1000

Correlation r= 0.9

Calculate the values A,B,C and D (1 mark)

Future value of X	Z score of X	Predicted y =average of y+ r*(Z score of X)* standard deviation of y
595	A	B
600	0	$5000
615	C	D
