Question

A customer relations manager is interested to know how long it takes for customers to fill out extended warranty forms for a particular product. Data below shows the time to fill out the forms by 11 customers. Test, at 5% level, whether the median time to fill out the forms exceeds 3 minutes.

Customer	Fill Time (minutes)
1	3.7
2	2.8
3	3.2
4	3.9
5	4.4
6	3.1
7	3.5
8	5.4
9	3
10	3.7
11	4.5

State the hypotheses.
What statistical test should be used to determine if the median time to fill out the forms exceeds 3 minutes.?
Set up the decision rule. (α=0.05)
Compute the test statistic and find the p-value.
Interpret your results.
Give your conclusion.

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
