QUESTION 4 A study was conducted by the Research Department of Agrofruity Company to determine the relationship between the amount of fertilizer used and the yield of mango fruit in their plantation. The data collected were as follows: Amount of fertilizer (gm) Unit of fruits 150 100 175 115 190 125 200 150 75 60 150 100 190 90 140 80 The Minitab output for the above study is as follows: Regression Analysis: Unit of fruits versus Amount of fertilizer (gm) The regression equation is Unit of fruits - 12.3 + 0.568 Amount of fertilizer (gm) Predictor Coof SE Coef T Constant 12.28 25.73 0.48 0.650 Amount of fertilizer (gm) 0.5683 0. 1577 3.60 0.011Draw a scatter diagram for the above study.
