Timothy, a javelin thrower, has a sample throw mean of 72.7 meters from 23 throws. Timothy still claims that his average throw is 65 meters, and the high average can be attributed to chance. At the 2% significance level, does the data provide sufficient evidence to conclude that Timothy's mean throw is greater than 65 meters? Given the sample data below, accept or reject the hypothesis.
- H0:=65meters; Ha:>65meters
- =0.02 (significance level)
- z0=2.14
- p=0.0162
