Why? For the data in Exercise 15.10, find the standard error of estimate, then construct the 95% prediction interval for boat trailer sales during a year in which the number of boats sold is 500,000. In exercise In regression and correlation analysis, what are the two components of the total amount of variation in the y values? Define the coefficient of determination in terms of these components. For n = 37 data points, r2 = 0.29. At the 0.02 level of significance, can we conclude that the true coefficient of correlation could be zero?
