,1. A farmer is modelling the relationship between the amount of nitrogen applied to wheat
and the percentage of protein in the wheat at harvest.
DO NOT WRITE IN THIS AREA DO NOT WRITE IN THIS AREA DO NOT WRITE IN THIS AREA
A sample of 12 fields of wheat is taken at harvest and the amount of nitrogen applied
to the wheat, x kg/hectare, and the percentage of protein in the wheat at harvest, y, are
both recorded.
Some summary statistics are given below.
x 1700
y 140.1
y 2
1646.45 Sxx = 41 366.67 Sxy = 597.5
(a) Find the product moment correlation coefficient between x and y
(3)
(b) Explain whether the answer to part (a) is consistent with a linear model for
these data.
(1)
The farmer wants to increase the percentage of protein in the wheat at harvest, y, by 2
(c) Estimate the amount of additional nitrogen that should be applied.
(3)
Three possible lines are proposed to model the data. The table shows some summary
statistics for each of the lines.
Residual sum of
Line Sum of residuals
squares (RSS)
A 0 4.03
B –0.2 2.15
C 0 2.15
One of the lines is the correct linear regression line for these data.
(d) State which of line A or line B or line C is the correct linear regression line for
these data.
Give a reason for your answer.
