Using SPSS This exercise requires the use of a computer package. A study on the effect of applying fertilizer in bands is described in the article "Fertilizer Placement Effects on Growth, Yield, and Chemical Composition of Burley Tobacco" (Agronomy Journal [1984]: 183- 188). The accompanying data were taken from a scatterplot appearing in the article, with y = plant Mn (mg/g dry weight) and x = distance from the fertilizer band (cm). The authors suggest a quadratic regression model

x 0 10 20 30 40

y 110 90 76 72 70

a. Use a suitable computer package to find the estimated quadratic regression equation.

b. Perform the model utility test.

c. Interpret the values of R2 and Se.

d. Are both the linear and quadratic predictors important? Carry out the necessary hypothesis tests and interpret the results.

e. Find a 90% confidence interval for the mean plant Mn for plants that are 30 cm from the fertilizer band
