¿(P - P)
The manufacturer of the new javelin claims that the new javelin model will improve lengths of
throws.
Hi represents the population mean throw length of the old javelin model.
Hz represents the population mean throw length of the new javelin model.
ZH = In:°H
Ha:Hi < Hz (Claim)
At the 0.01 level of significance, is there enough evidence to reject Ho and support the
manufacturer's claim?
A. Yes, the test statistic t = -3.66 is in the rejection region with critical value -3.7469
B. No, the test statistic t = -3.66 is not in the rejection region with critical value -3.7469
C. Yes, the test statistic t = -3.71 is in the rejection region with critical value -3.66
D. No, the test statistic t = -3.75 is not in the rejection region with critical value -3.66
E. Yes, the test statistic t = –3.75 is in the rejection region with critical value -3.7469
