Question

A team of researchers hypothesized that men and women use different strategies to maintain happiness. They surveyed men and women and asked which of the following three strategies they used to maintain happiness (participants had to choose only one): friends, exercise, or academic accomplishments. Among the men, 97 indicated friends, 116 indicated exercise, and 21 indicated academic accomplishments. Among the women, 89 indicated friends, 98 indicated exercise, and 77 indicated academic accomplishments. Calculate the expected frequency for men who use exercise to maintain happiness, if there was no relationship between sex and happiness strategy.
