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. We have enough evidence in the data to dispute the store's claim that the mean waiting time is less than four minutes. G. a = 0.05 H. p-value = 0.0789 1. p-value = 0.9211 JHO: > 4 Ha: μ = 4 K.
