Question: A farmer sprayed two rows of flowering plants, Row 1 and Row 2, each with a different type of fertilizer. - Each row received the same amount of sunlight and water. - After several weeks, the farmer selected every third plant in each row and counted the number of flowers on those plants. - The farmer calculated the mean and the mean absolute deviation of the number of flowers on the plants in each row. Based on the results, the farmer determined that Row 2 had the greater number of flowers per plant, and the lesser amount of variation in the number of flowers per plant. Which of the following could have been the farmer's results?
A) Row 1: mean =10.2, mean absolute deviation =0.39 Row 2: mean =14.9, mean absolute deviation =2.2
B) Row 1: mean =10.2, mean absolute deviation =2.2 Row 2: mean =14.9, mean absolute deviation =0.39
C) Row 1: mean =14.9, mean absolute deviation =0.39 Row 2: mean =10.2, mean absolute deviation =2.2
D) Row 1: mean =14.9, mean absolute deviation =2.2 Row 2: mean =10.2, mean absolute deviation =0.39
