Question

A recent study of undergraduates looked at gender differences in dieting trends. There were 185 women and 105 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		39		9
No

(a) Fill in the missing cells of the table.

		Gender
Tried low-fat diet		Women		Men
Yes		39		9
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.)

χ2	=
df	=
P-value	=

Summarize the results.

There is strong evidence at the 5% level that gender and the likelihood of trying a low-fat diet are related.
