The number of incoming phone calls at a company switchboard during 1-minute intervals is believed to have a Poisson distribution. Use = .10 and the following data to test the assumption that the incoming phone calls follow a Poisson distribution.

Compute the value of the test statistic (to 2 decimals).

The *p* value is Select less than .005 between .005 and .01 between .01 and .025 between .025 and .05 between .05 and .10 greater than .10 Item 2

What is your conclusion?

Select Cannot reject assumption that the data comes from a Poisson distribution The data does not come from a Poisson distribution Item 3
