Write a model that relates both variables
Consider the following data extracted from agricultural publications.
Year 1971 1972 1973 1974 1975 1976 1977 1978 1979 1980
Fertilizer used(unit) 6 10 12 14 16 18 22 24 26 32
Cornproduced (bushels) 40 44 46 48 52 58 60 68 74 80
(a) Plot a scatter diagram for the set of observations.
(b) Write a model that relates both variables.
(c) Estimate the parameters of the model, present the results in standard form and then interpret them.
(d) Suppose that in 1981,the farmer planned to use 36 units of fertilizers, determine the expected impact on corn production.
