BUAD 310 Fall 2009 Minitab Project 8 1.) S = 83.4624 and 83.4624 2 = 6966 2.) Confidence Interval (15.2, 83.9) 3.) PI (-100.1, 199.3) 4.) 1. H 0 : B 1 = 0 vs H 1 : B 1 does not = 0 2. Since P value = .338 > 10% we do not reject H 0 3. Thus the S&P % returns are no useful for predicting AAPL % returns in the population 5.) 1. H 0 : B 1 < 1 vs H 1 : B 1 > 1 T = (B 1 – 1)/S

Unformatted text preview: B1 (1.25-1)/1.261 = .1983 CDF(.1983) = .577346 2. We do not reject H 3. Thus AAPL is not more risky 6.) 1. H : B = 0 vs H 1 : B does not = 0 2. Since P value = .126 &gt; 5% we do not reject H 3. Thus the claim is justified 7.) Plug in the average of S&amp;P 8.) Using 95% CI (8.4, 92)...
