Question

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.

Answer 1

1.

Mean body temperature

2.

Treatments

3.

5 levels (Placebo, Aspirin,...., Buffering)

k = 5

4.

Replicates per level = 7

Total Sample size = 35

Balanced Design since each level has an equal number of replicates.
