Please answer the questions correctly please and explain it clearly as well.

Question 3:

The following sample observations were randomly selected:(Round the final answers to 3 decimal places.)

X: 5 13 6 9 7

Y: 3 21 17 7 16

a.Determine the standard error of estimate.

Standard error

b.Suppose a large sample is selected (instead of just five). About 95% of the predictions would be between what two values? Assuming that the Standard Error of Estimate does not change.

Y'

Question 4:

The following sample observations were randomly selected:(Round the final answer to 4 decimal places.)

X: 18 1 20 6 12 20 3 2

Y: 21 23 11 8 18 18 4 5

a.Determine the standard error of estimate.

b.Suppose a large sample is selected (instead of just eight). About 95% of the predictions would be between what two values? Assuming that the Standard Error of Estimate does not change. Usez= 2.
