A horticulturist is studying the relationship between tomato plant height and fertilizer amount. Thirty tomato plants grown in similar conditions were subjected to various amounts of fertilizer (in ounces) over a four-month period, and then their heights (in inches) were measured. Height Fertilizer 20.4 1.9 49.2 5.0 ⋮ ⋮ 46.4 3.1 Click here for the Excel Data File a. Estimate the model: Height = β0 + β1Fertilizer + ε. (Round your answers to 2 decimal places.) Heightˆ = + Fertilizer b-1. Interpret the coefficient of Fertilizer. (Round your answer to 2 decimal places.) b-2. Does the y-intercept make practical sense? multiple choice Yes, since the y-intercept is positive. No, since the y-intercept is positive. Yes, since some farmers may not use any fertilizer. No, since some farmers may not use any fertilizer. c. Use the estimated model to predict, after four months, the height of a tomato plant which received 3.0 ounces of fertilizer. (Round coefficient estimates to at least 4 decimal places and final answer to 2 decimal places.)
