An advertising agency wants to know if the magazine they advertise in makes a difference in the response to the magazine readers. Each reader was asked to give the advertisement a rank between 0 and 10 (0 for no interest to 10 with high interest). They then survey 10 people that read one of the three different magazines that the company was interested in advertising in. The response of those ten people are:
| Sports Illustrated |
Home and Garden |
In Magazine |
| 5 |
5 |
8 |
| 4 |
7 |
8 |
| 7 |
3 |
5 |
| 8 |
At a significance level of .05 can we conclude that the mean rank for the advertisement is the same for all three of the magazines?
