Could you please answer these questions from A to H?

1) Many soil-born pathogens are sensitive to soil pH. As a pota studying effects of sulpher application on scab disease of potatoes. Your t 250, 500, and 750 lbs of sulpher per hectare. Your experimental unit is the uniform soil condistions and past management history. One-tenth acr sulpher in the fall. Assignment of sulpher treatment to plots is random, The index" calculated by estimating the percent surface area of a potato select 50 potatoes from each one-te potato scientist, you are interested in otatoes. Your treatments are 0 (control) e. Your experimental unit is the study field with relativey One-tenth acre plots are treated with the data you collect are a "scab covered with scab. You randomly nth acre plot, estimate the scab index, and average across the 50 potatoes. Your data are: Treatment (Ibs sulpher/acre 250 30 500 25 30 25 750 20 Replicate 0 40 30 50 40 15 4 2040 10 20 A) Specify the model both in statistical terms and biological terms B) For the experiment, draw an example (one of many possibilities) of the layout in the field. C) What assumptions are necessary to carry out the ANOVA? D) Test for normality, report and interpret the result. E) Test for homogeneous variances, report and interpret the result. F) Complete the ANOVA by hand and summarize in tabular form. G) Specify null and alternate hypotheses H) Interpret both statistically and biologically the outcome of the experiment.
