show your work please

Given the following data, answer the following questions:
(Assume the second column to be the dependent variable)
a) Construct the scatter diagram.
b) Compute the linear correlation coefficient r and value of r-critical.
c) Is r statistically significant at an alpha of 5%?. Explain why or why not
d) What is the standard error of regression?
e) Identify any outliers (do not remove them). Show your work. If no outliers, indicate N/A
f) Compute the equation of line of best fit
g) Perform a hypothesis to test the claim of a linear relationship at 5%?
