The owner of a mobile ice-crane believes that hot weather affects his sales. To investigate the effect on his business, he collected data on his daily sales"P" and the maximum temperature "T" on each of the 20 days. He then coded the data using x = T-20 and y = P-300. And calculated the summary statistics given below Ex = 57 Ey = 2222 Ex2 401 Ey? 305576 Exy 3871 a. Find the Product Moment Correlation Coefficient (PMCC) b. Calculate the probable error of the correlation coefficient above in "a" c. Find an equation of the regression line of P on T
