Ruby, a bowler, has a sample game score mean of 170.4 from 27 games. Ruby still claims that her average game score is 199, and the low average can be attributed to chance. At the 1% significance level, does the data provide sufficient evidence to conclude that Ruby's mean game score is less than 199? Given the sample data below, accept or reject the hypothesis.
H0:μ=199
Ha:μ<199
z=−0.55
p=0.2912
Select the correct answer below:
Reject the null hypothesis because |−0.55|>0.01.
Reject the null hypothesis because the p-value 0.2912 is greater than the significance level α=0.01.
Do not reject the null hypothesis because |−0.55|>0.01.
Do not reject the null hypothesis because the p-value 0.2912 is greater than the significance level α=0.01.
Reject the null hypothesis because the value of z is negative.
