In a simple linear regression analysis, it is found that b1 = 2.556 and s (b1) 4.122. The sample size is n = 22. Conduct an F test for the existence of a linear relationship between the two variables. For the American Express example, give a 95% prediction interval for the amount charged by a member who traveled 5,000 miles. Compare the result with the one for x = 4,000 miles. Consider the following sample data of X and Y: X Y 8 ............ 22.30 6 ............ 16.71 9 ............ 25.21 6 ............ 15.84 1 ............ 2.75 8 ............ 21.22 2 ............ 5.27 1 ............ ...1.
