6. Resenhoeft, Villa, and Wiseman (2008) conducted a study showing that a woman shown in a photograph was judged as less attractive when the photograph showed a visible tattoo compared to the same pho- tograph with the tattoo removed. Suppose a similar experiment is conducted as a repeated-measures study. A sample of n = 12 males looks at a set of 30 photographs of women and rates the attractiveness of each woman using a 5-point scale (5 = most posi- tive). One photograph appears twice in the set, once with a tattoo and once with the tattoo removed. For each participant, the researcher records the difference between the two ratings of the same photograph. On average, the photograph without the tattoo is rated Mp = 1.2 points higher than the photograph with the 33 for the difference scores. Does tattoo, with SS the presence of a visible tattoo haye a significant %3D

Suppose a similar experiment is conducted as a repeated-measures study.

One photograph appears twice in the set, once with a tattoo and once with the tattoo removed. For each participant, the researcher records the difference between the two ratings of the same photograph. On average, the photograph without the tattoo is rated MD = 1.2 points higher than the photograph with the tattoo, with SS = 33 for the difference scores. Does the presence of a visible tattoo have a significant effect on the attractiveness ratings? Use a two-tailed test with a = ,05.
