Question

The data for the production of wheat in tons (X) and the price of a kilo of flour in pesetas (Y) in Spain during the 80s are as follows: Wheat production: 30, 28, 32, 25 Flour price: 25, 30, 27, 40 a) Compute the correlation, r. (Report your answer to one decimal place.) b) Compute the equation of the regression model. (Report your answer in integers) c) Compute the residuals d) Compute the standard error of the estimate, se. (Report your answer to one decimal place.) e) Compute R-square. (Report your answer to two decimal places.)
