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 FEMALE 50 60 MALE 120 170 a. State null and alternative hypotheses...
