Kenneth, a competitor in cup stacking, claims that his average stacking time is 8.2 seconds. During a practice session, Kenneth has a sample stacking time mean of 7.8 seconds based on 11 trials. At the 4% significance level, does the data provide sufficient evidence to conclude that Kenneth's mean stacking time is less than 8.2 seconds? Accept or reject the hypothesis given the sample data below.

• H0:μ=8.2seconds;Ha:μ<8.2seconds
• α=0.04(significance level)
• z0=-1.75
• p=0.0401

Select the correct answer below

a. Do not reject the null hypothesis because the p-value 0.0401 is greater than the significance level α=0.04.

b. Reject the null hypothesis because the p-value 0.0401 is greater than the significance level α=0.04.

c. Reject the null hypothesis because the value of z is negative.

d. Reject the null hypothesis because |-1.75|>0.04.

e. Do not reject the null hypothesis because |-1.75|>0.04.
