Right tail = 28.869
left tail = 14.041
29 degrees of freedom left tail .975 = 16.047 .025 = 45.722

0.01 with 14 degrees of freedom is 0.01=29.1
Skip but feel free to sketch on a piece of paper for your benefit.
statistics is greater than the critical value. the researcher will not reject the null hypothesis
13. Feel free to use any method you want. If you use the classical method please report the value of your test statistic and your decision. Likewise if you use the pvalue method please state your pvalue and your decision. Hint: The sample standard deviation (s) is 15.20.
test statistic is 6.422. because the test stastic is 6.42 is greater than the critical value 3.325 the null hypothesis is rejected. there is no evidence that the level of significance that the standard deviation is less than 18 seconds
15. Feel free to use any method you want. If you use the classical method please report the value of the test statistic and your decision. Likewise if you use the pvalue method please state your pvalue and your decision.
Test statistic = 15.639 Since the test statistic is less than the critical value the null hypothesis is rejected. level of significance support the claim that rose is more consistent that the other SG in the NBA
