Multiple Choice

Refer to the information provided in Scenario 22.4 below to answer the question(s) that follow.
SCENARIO 22.4: In a randomized 1-year trial of 400 Mr. Lincoln hybrid tea rose bushes with rose rosette disease, 200 are slated to receive only a sulphur treatment (we will call this Group A) , and the other 200 are slated to receive the sulphur treatment and an additional neem oil treatment 4 months later (we will call this Group B) . Assume that the neem oil treatment is ineffective in treating rose rosette disease, so on average, the same proportion of rose bushes in each group will die of the disease. In Group B, 25 of the 200 rose bushes die in the 4-month period leading up to the neem oil treatment. Of the 175 bushes left, 25 die in the 8 months following the neem oil treatment. Since we know the neem oil treatment is ineffective, the rose bushes in Group A will, on average, suffer the same fate as those in Group B, with 25 bushes dying in the first 4 months and another 25 dying in the following 8 months.
-Related to the Economics in Practice on p. 727: Refer to Scenario 22.4. For Group A, what is the rate of death due to rose rosette disease?

• A) 5%
• B) 12.5%
• C) 25%
