TABLE 10-10
The following EXCEL output contains the results of a test to determine if the proportions of satisfied guests at two resorts are the same or different.

Quizplus · Accepted Answer

The test conducted is a two-sample proportion test, where the null hypothesis is that the proportions of satisfied guests in the two resorts are equal. The alternative hypothesis is that the proportion of satisfied guests in Resort 1 (Group 1) is higher than in Resort 2 (Group 2). The p-value for this alternative hypothesis is given as 0.00262. Since it is a one-sided test where the alternative hypothesis is in the upper tail, the p-value needs to be divided by 2 to get the area in the upper tail. Therefore, the p-value of the test will be 0.00262/2.
