Eric wаnts tо investigаte the relаtiоnship between the number оf tomatoes a plant produces and the number of aphids he finds on the plant. He takes a sample of five plants from his garden at random and gathers the following data: Plant Number of Tomatoes Number of Aphids 1 12 4 2 10 7 3 6 6 4 5 12 5 3 20 Note the following information: The mean number of aphids is 9.8. The SD of the number of aphids is 6.4 The mean number of tomatoes is 7.2. The SD of the number of tomatoes is 3.7. The correlation between the number of aphids and the number of tomatoes is -0.82. Calculate the slope and intercept for a linear regression model with number of tomatoes as the response variable. Then, predict the number of tomatoes on a plant with 10 aphids.
