Instructors Gave Caffeine to Fruit Flies to See If It

question 11

Multiple Choice

Instructors gave caffeine to fruit flies to see if it affected their rest. The three treatments were a control, a low caffeine dose of 1 mg/ml of blood, and a higher caffeine dose of 5 mg/ml of blood. Fifteen fruit flies were assigned at random to three treatments, five to each treatment. The minutes of rest measured over a 12-hour period were recorded; the data follow. Minitab was used to obtain 95% simultaneous confidence intervals for the differences in means among the three treatments using Tukey's procedure; the results follow. From these intervals:

• A)there is not sufficient evidence to conclude that  _control   _low.
• B)there is sufficient evidence to conclude that  _control   _high.
• C)there is sufficient evidence to conclude that  _high   _low.
• D)All of the answer options are correct.
