Forecasting
The Agricultural Extension Agent's Office has tracked fertilizer application and crop yields for a variety of chickpea and has recorded the data shown in the following table. Their staff statistician developed the regression model and computed the performance statistics displayed below the data.
See the attached picture for the data.
1) Use the information provided in Table 14.1. What percent in the variation of the variable Bushels is explained by the value of the variable Fertilizer?
2) Use the information provided in Table 14.1. For every unit of fertilizer applied, the crop yield increases by:
3) Use the information provided in Table 14.1. The value of Bushels when Fertilizer is 60 is:
4) Use the information provided in Table 14.1. The value of Fertilizer required to generate 100 bushels yield must be:
5) Use the information in Table 14.1. If the correlation coefficient were negative, what would also be true?
Please include all the steps involved so that I can reproduce it with a different problem.
