One Sample T: Test ofHO: u : 12 versus H1: u at 12 Sample Std. Std Error Deviation (SE) of Mean x 15 12.564 0.0936034 ? ? ? (a) How many degrees of freedom are there on the t-test statistic? (b) Fill in the missing values. You may calculate the bounds on the P-value. What conclusions would you draw? (c) Is this a one-sided or a two-sided test? (d) Construct a two-sided CI on the mean. (e) If the hypothesis had been H0: 14 = 12 versus H1: u > 12, would your conclusion change? (i) If the hypothesis had been H0: u = 11 versus H1: u 7E 11, would your conclusion change? Answer this question by using the CI computed in part ((1)
