A story describing a date rape was read by 352 high school
students. To investigate the effect of the victim’s clothing on
subject’s judgment of the situation described, the story was
accompanied by either a photograph of the victim dressed
provocatively, a photo of the victim dressed conservatively, or no
picture. Each student was asked whether the situation described in
the story was one of rape. Data from an article are given in the
accompanying table. Is there evidence that the proportion who
believe that the story described a rape differs for the three
different photo groups? Test the relevant hypotheses using
α = .01. (Use 2 decimal places.)
| Response | Picture | ||
| Provocative | Conservative | No Picture | |
| Rape | 80 | 103 | 91 |
| No Rape | 49 | 12 | 17 |

The data —Select—supportdo not support the conclusion that the
proportion who believe the story describes a rape is not the same
for the three photo groups.
