STATISTICS MISC - Construct Hypothesis Test for Proportions - ExcelMary, 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:μ=61 meters ; Ha:μ61 meters • α=0.01 (significance level) Reject the null hypothesis because the p -value 0.0233 is greater than the significance level α=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 α=0.01 . Answer Explanation Correct answer: Do not reject the null hypothesis because the p -value 0.0233 is greater than the significance level α=0.01 .
