Question

Christina, a javelin thrower, has a sample throw mean of 62.3 meters from 29 throws. Christina still claims that her average throw is 57 meters, and the high average can be attributed to chance. At the 2% significance level, does the data provide sufficient evidence to conclude that Christina's mean throw is greater than 57 meters? Given the sample data below, accept or reject the hypothesis.

• H0:=57meters; Ha:>57meters
• =0.02 (significance level)
• z0=2.61
• p=0.0045

Select the correct answer below:

Do not reject the null hypothesis because the value of z is positive.

Reject the null hypothesis because 2.61>0.02.

Do not reject the null hypothesis because 2.61>0.02.

Do not reject the null hypothesis because the p-value 0.0045 is less than the significance level =0.02.

Reject the null hypothesis because the p-value 0.0045 is less than the significance level =0.02.
