Question 2

Allotted time: 15 minutes (plus 5 minutes to submit) Students at an agricultural station conducted a study to compare genetically modied (GM) corn with regular corn. Each of 33 plots of land was divided into two half-plots; one half-plot was randomly selected to be planted with the GM corn, and the other half-plot was planted with the regular corn. e table shows summary statistics for the yields, in bushels per acre, and the dierence in yield (GM minus regular) for each plot.

(a) Explain why the yields from one type of corn are not independent of the yields from the other type of corn. (b) Based on the summary statistics, would it be more likely to obtain a yield of 123 or more bushels per acre from a plot of GM corn or a plot of regular corn? Justify your answer. A boxplot of the dierences in yield is shown below. Dierence in yield (bushels per acre, GM minus regular) (c) Describe the distribution of the dierences.

?e students conducted a test of the hypotheses H 0 :µ d =0 H a :µ d 0, where µ d is the population mean dierence (GM minus regular) in yield, in bushels per acre, for plots similar to those used in the study. e conditions for inference have been met. (d) One of the conditions for inference that was met is that the sample size of the dierences is greater than 30. Explain why it is necessary to satisfy this condition. (e) e test resulted in a -value of 0.0003. Based on the -value, what conclusion should the students make?
