Do Men and Women Differ in the Way They Rate

Short Answer

Do men and women differ in the way they rate the cuteness of babies? In a study, a team of researchers examined whether gender differences existed in ratings for infants. The data below show average ratings by male and female participants for infant pictures. The team used a Mann-Whitney U test to compare the two groups. Higher scores indicate that the participant thought the image represented a cuter baby.
$$\begin{array} { l l } \hline \text { Men } & \text { Women } \\\hline 7.5 & 8.5 \\6.4 & 6.6 \\3.7 & 7.5 \\8.9 & 6.9 \\4.5 & 7.3 \\6.7 & 4.6 \\5.3 & 7.7 \\5.7 & 8.8 \\6.8 & 9.4 \\7.0 & 9.7 \\\hline\end{array}$$ Calculate the Mann-Whitney U-test U-value and determine the smaller of the two values.
