Chapter 19, Problem 25CE
The producer of a candy bar, called the “King James” Bar, reports on the package that the calorie content is 420 per 2-ounce bar. A sample of five bars from each of the last 10 days is sent for a chemical analysis of the calorie content. The results are shown next. Does it appear that there are any days where the calorie count is out of control? Develop an appropriate control chart and analyze your findings.

Penicillin is produced by the Penicillium fungus, which is grown in a broth whose sugar
content must be carefully controlled. Several samples of broth were taken on each of three
successive days, and the amount of dissolved sugars (in mg/mL) was measured on each
sample. The results were as follows:
Day 1

a) State the appropriate hypotheses to test for a difference in means.
b) Construct the appropriate ANOVA table.
c) Use the ANOVA table from part b) to test whether there is a difference in the mean
amount of dissolved sugars between the three days at the .05 level.
d) Is it applicable to follow up with Tukey-Kramer pairwise comparisons? If so,
determine which pair(s) of means are significantly different using the Tukey-Kramer
method. If not, explain why not.
