Question

Functional foods are those containing nutritional supplements in addition to natural nutrients. Kolodinsky, et al. (2009) examined attitudes toward functional foods for college students. For American students, the results indicated that females had a more positive attitude toward functional foods and were more likely to purchase them compared to males. In similar study, a researcher asked students to rate their general attitude toward functional foods on a 7-point scale (higher score is more positive). The results are as follows:

Females	Males
n=8	n=12
M=4.69	M=4.43
SS=1.60	SS=2.72

a. Do the data indicate that females have a more positive attitude toward functional foods than males? Use α = .05

b. Compute the 95% confidence interval.
