You manage a call center and are concerned that the calls coming into the center are not evenly distributed.
You monitor 500 incoming support calls and obtain the following information:
|
Minutes/Call
|
Observed counts
|
|
? 1
|
96
|
|
< 1 and ? 2
|
79
|
|
< 2 and ? 3
|
101
|
|
< 3 and ? 4
|
44
|
|
< 4 and ? 5
|
180
|
|
Total

Using the chi-square test determine if you can conclude that the difference between the observed counts is different from an evenly distributed count or if the difference could have happened by chance at the 0.05 level of significance.
