¿(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.
Ho:H1 = H2
Hai 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
Expert Solution
Step 1
Two samples are called paired samples if the sample data is collected using same elements but under two different conditions. The paired sample t test is used to compare the mean of such data.
This test uses the difference in paired data as single sample. The test statistic is computed by , where is the mean difference, is population mean difference claimed in null hypothesis, is sample standard deviation of difference and n is sample size.
