5.8. Consider the MU281 population and the two variables RMT85 (= y) and P85 (= z). We want to estimate the slope, B = ()oxy)/(Coz#), of a regression line through the origin. An SI sample of size n = 50 is drawn and the following results are obtained: [s ZYK = 582,220; [, 2 = 72,768; ), zy = 4.13155 x 1010 Is 24 = 586,102,776; Es zyk = 4,911,948,478 Compute an approximately 95% confidence interval for B
