Using the data below:

(i) Find the regression line (showyour manual calculation, and do not use Excel )

(ii) compute the standard error of the estimate

(iii) calculate the estimated standard deviation of b1, and

(iv) use the t-test to test if there is a linear relationship exist between x and y.

Use α = .05.
