Investigators Gave Caffeine to Fruit Flies to See If It

question 23

Multiple Choice

Investigators gave caffeine to fruit flies to see if it affected their rest. The four treatments were a control, a low caffeine dose of 1 mg/ml of blood, a medium dose of 3 mg/ml of blood, and a higher caffeine dose of 5 mg/ml of blood. Twelve fruit flies were assigned at random to the four treatments, three to each treatment, and the minutes of rest measured over a 24-hour period were recorded. Assume the data that follow are four independent SRSs (one from each of the four populations of caffeine levels) and that the distribution of the yields is Normal. A partial ANOVA table produced by Minitab follows, along with the means and standard deviation of the yields for the four groups. The value of the ANOVA F statistic for testing equality of the population means of the average rest time for the four caffeine levels is:

• A)2.78.
• B)4.73.
• C)4.82.
• D)7.41.
