Consider the following sample data for two variables. x 2 4 3 6 8 y 3 4 4 4 8 a. Calculate the sample covariance. b. Calculate the sample correlation coefficient. c. Describe the relationship between x and y.

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

step-by-step explanation:

a negative exponent is translated as follows:

so, we have

a is the correct

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
