A. 14.5 B. 14.4 C. 14.8 D. 14.7 E. 14.6 10. (2 points) Compute the sample variation s2. A. 0.6733 B. 0.7033 C. 0.8433 D. 0.4033 E. 0.5633 11. ( 2 points) Let the null hypothesis be H0:=14 (and hence the alternative hypothesis is H1:>14). Compute the P-value. A. 0.0246 B. 0.0884 C. 0.2384 D. 0.3626 E. 0.0126 12. (2 points) What conclusion should we make? (No explanation is required.) A. P-value is significant and we accept the null hypothesis. B. P-value is not significant and we reject the null hypothesis. C. P-value is significant and we reject the null hypothesis. D. P-value is not significant and we do not reject the null hypothesis. E. P-value is not significant and we accept the alternative hypothesis
