Quizplus · Accepted Answer

To test the claim that "Resort 1 (Group 1) has a higher proportion of satisfied guests compared to Resort 2 (Group 2)", we need to conduct a one-tailed hypothesis test. 
Looking at the output, the p-value for the two-sample proportion test with a one-tailed alternative hypothesis (Ha: p1 > p2) is 0.00262. 
Since we are conducting a one-tailed test, we need to divide the p-value by 2 to get the area in one tail. 
Therefore, the correct answer is C) 0.00262/2.
