31) To determine if the average sales per week for store A is greater than the average sales per week for store B you take sales data on 12 weeks from each store. You test the hypothesis H, HA ≤ MB versus Ha: HA > MB and find a p-value of 0.62. To determine if the average sales per week depends on store, you wish to test the hypothesis Ho: A = HB versus Ha: HA MB. What is the p-value for this hypothesis test? A) 0.76 B) 0.38 C) 0.62 D) 0.31 E) 1.24

31) To determine if the average sales per week for store A is greater than the average
sales per week for store B you take sales data on 12 weeks from each store. You test
the hypothesis Ho: HA ≤ HB versus Ha: HA > μg and find a p-value of 0.62. To
determine if the average sales per week depends on store, you wish to test the
hypothesis Ho: A = μB versus Ha: HAMB. What is the p-value for this hypothesis
test?
A) 0.76
B) 0.38
C) 0.62
D) 0.31
E) 1.24
