Question

Mary, a javelin thrower, claims that her average throw is 61 meters. During a practice session, Mary has a sample throw mean of 55.5 meters based on 12 throws. At the 1% significance level, does the data provide sufficient evidence to conclude that Mary's mean throw is less than 61 meters? Accept or reject the hypothesis given the sample data below.

• H0:=61meters; Ha:<61meters
• =0.01 (significance level)
• z0=1.99
• p=0.0233

Select the correct answer below:

Reject the null hypothesis because |1.99|>0.01.

Do not reject the null hypothesis because |1.99|>0.01.

Reject the null hypothesis because the p-value 0.0233 is greater than the significance level =0.01.

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

Do not reject the null hypothesis because the p-value 0.0233 is greater than the significance level =0.01.
