The following table contains the average number of employees per 100 hectares (x) and the production rate per 100 hectares (y) at 15 different farms in a region. x M 00 405 16.3 696 11 510 6.6 384 9.4 461 11.3 491 9.2 395 9.9 499 7.4 309 5.3 278 6 290 11.8 597 17.1 710 14.2 556 6.2 242

Assume that the averages are jointly normally distributed, (a) Find a regression line relating the production rate to the number of employees, Round your answers to one decimal place (es. 98.7). BA (b) Test for the significance of regression using a = 0.1. hypothesis that i = 0. (c) Estimate the correlation coefficient. Round your answer to three decimal places (e.g. 98.765). (d) Test the hypothesis that p = 0, using a = 0.1 hypothesis that p = 0. (e) Test the hypothesis that p = 0.1, using a = 0.1. hypothesis that p = 0.1. (f) Construct a 90% confidence interval for the correlation coefficient. Round your answers to three decimal places (e.g. 98.765). sps Save forte
