A trial evaluated the fever-inducing effects of three
substances. Study subjects were adults seen in an emergency room
with diagnoses of the flu and body temperatures between 100.0 and
100.9ºF. The three treatments (aspirin, ibuprofen and
acetaminophen) were assigned randomly to study subjects. Body
temperatures were reevaluated 2 hours after administration of
treatments. The below table lists the data.

A student ran a between-subjects experiment comparing three treatments for depression: cognitive-behavioral therapy (CBT), client-centered therapy (CCT), and a no-treatment condition. Subjects were randomly assigned to the experimental condi- tion. After a sufficient duration on these treatments, the difference in subject’s depression scores pre/post study were measured using a valid depression assessment instrument. The data are summarized in the tables below. Conduct a Oneway ANOVA with α = 0.05 by first completing the values in the lower table, then using...
2. An experiment was conducted to compare five treatments for reducing fever. Thirty-five patients were randomly assigned into five treatment groups. The patients' temperatures were taken two hours after receiving the treatment, and are given below. We will test the claim that there is no difference in mean body temperature among each of the five treatment groups using a 5% significance level. Placebo Aspirin Anacin Tylenol Bufferin 98.3 96.0 97.2 95.1 96.1 98.7 96.6 97.4 95.7 96.5 98.1 95.3 96.9...
Transistor Manufacturing Study: A transistor manufacturer conducted an experiment to investigate the effects of three factors on PRODUCTivity (measured in thousands of dollars of items produced) per 40-hour week. The factors were as follows: Length of work week in DAYS (two levels): Five consecutive 8-hour days or four consecutive 10-hour days SHIFT (two levels): day or evening shift Number of coffee BREAKS (three levels): 0, 1, or 2 The experiment was conducted over a 24-week period with the 2 ×...
In Data 4.1 on page 258, we examine a study in which mice were randomly assigned to either a normal light/dark cycle or to have a light on around the clock. According to the paper describing that study, "The global increase in the prevalence of obesity and metabolic disorders coincides with the increase of exposure to light at night." The study is examining whether light at night plays a causal role in the obesity epidemic. In Data 4.1, we examine...
