A food store advertises that their checkout waiting times is four minutes or less. An angry customer wants to dispute this claim. He takes a random sample of shoppers at the peak time and records their checkout times. Can he dispute their claim at significance level 10%? Checkout times: 3.8, 5.3, 3.5, 4.5, 7.2, 5.1 Match the following steps in hypothesis testing. -Step 1 - ✓ Step 2 -✓ Step 3 - ✓ Step 4 -✓ Step 5 Step 6 A. Ho: p = 4 Ha: p < 4 B. Ho: #4 Ha: p=4 C. t = 1.6598 D. a = 0.10 We have not enough evidence in the data to dispute the store's claim that the mean waiting time is less than four minutes. F.
