Answer:
The data does not provide sufficient evidence to conclude that Kenneth's mean stacking time is less than 8.2 seconds.
Do not reject the null hypothesis because the p-value 0.0401 is greater than the significance level.
Step-by-step explanation:
Null hypothesis (H0): mu = 8.2 seconds
Alternate hypothesis (Ha): mu < 8.2 seconds
Significance level = 0.04
p-value = 0.0401
Using the p-value approach for testing hypothesis, do not reject H0 because the p-value 0.0401 is greater than the significance level 0.04.
There is not sufficient evidence to conclude that Kenneth's mean stacking time is less than 8.2 seconds.
