Question

A study was conducted to compare the amount of salt in potato chips. Random samples of
three varieties were obtained and the amount of salt in each 1-oz portion of potato chips was
recorded. Assume the populations are normally distributed with equal variances. The
results are given here:
BBQ
Cheese-
Amount of salt (in mg of sodium)
338, 159, 240, 190
235, 251, 233, 255, 260
Variety
flavored
Olestra-based
164, 150, 149, 170
a) Identify the explanatory variable.
b) Identify the response variable.
c) State the appropriate hypotheses to test for a difference in means.
d) The appropriate analysis to test for a difference in means would be:
a. One-way ANOVA
b. Two-way ANOVA
c. Three-way ANOVA
d. Two-Sample t-test
e) Construct the appropriate ANOVA table.
f) Use the ANOVA table from part b) to test whether there is a difference in the mean
amount of salt among the three types of potato chips at the .05 level.
