Question 630 • English Language Arts 10 - Second Semester
An avid traveler is investigating whether travel websites differ in their pricing. She chooses a random sample of 32 hotel rooms from across the state and notes the price of each room from site A and site B. The mean difference (site A – site B) in the prices for the rooms is $5.49 with a standard deviation of $18.65.
Answer
A
Because the P-value is less than α, there is evidence that the prices of hotel rooms from site A and site B are different, on average.
B
Because the P-value is greater than α, there is evidence that the prices of hotel rooms from site A and site B are different, on average.
C
Because the P-value is less than α, there is not sufficient evidence that the prices of hotel rooms from site A and site B are different, on average.
D
Because the P-value is greater than α, there is not sufficient evidence that the prices of hotel rooms from site A and site B are different, on average.
