A recent study of undergraduates looked at gender differences in dieting trends. There were 188 women and 103 men who participated in the survey. The table below summarizes whether a student tried a low-fat diet or not by gender:
| Gender | ||||
|---|---|---|---|---|
| Tried low-fat diet | Women | Men | ||
| Yes | 40 | 8 | ||
| No | ||||
(a) Fill in the missing cells of the table.
| Gender | ||||
|---|---|---|---|---|
| Tried low-fat diet | Women | Men | ||
| Yes | 40 | 8 | ||
| No | ||||
(b) Summarize the data numerically. What percent of each gender has
tried low-fat diets? (Round your answers to two decimal
places.)
| women | % |
| men | % |
(c) Test that there is no association between gender and the
likelihood of trying a low-fat diet. (Round your
χ2 to three decimal places, and round your
P-value to four decimal places.)

A recent study of gender preferences among car shoppers found
that men and women equally favor economy cars. A marketing analyst
doubts these results. He believes that a person’s gender influences
whether or not he/she purchases an economy car. He collects data on
400 recent car purchases cross-classified by gender and type of car
(economy car versus noneconomycar). The results are shown as
follows:
ECONOMY CAR
NON-ECONOMY CAR

A study of working actors looked at age and gender. One sample
of 50 male actors had a mean age of 23 and a standard deviation of
2. The other sample included 50 female actors with a mean age of 24
and a standard deviation of 3. Estimate with 87% confidence the
difference between the average ages of working male (μ1) and female
(μ2) actors. Round answers to the nearest hundredth.

The data in tab "Gender and Grades" shows the results of a
recent study regarding gender and grades. We want to determine if
gender and grades are independent. Use a 3% level of significance
to test this. State the null and alternative hypotheses.
