The correlation between two scores X and Y equals 0.75. If both scores were converted to z-scores, then the correlation between the z-scores for X and z-scores for Y would be (4 points) 1)

−0.75

2)

0.25

3)

−0.25

4)

0.0

5)

0.75

The correlation between two scores X and Y equals 0.8. If both the X scores and the Y scores are converted to z- scores, then the correlation between z- scores

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
