In Exercise 8.2-10, growth data are given for plants in normal air and for plants in CO2-enriched air. Those data are repeated here:

In this exercise, we shall test the null hypothesis that the medians are equal, namely, H0: mX = mY, against the alternative hypothesis H1: mX < mY. You may select the significance level. However, give the approximate p-value or state clearly why you arrived at a particular conclusion, for each of the tests. Show your work.

(a) What is your conclusion from the Wilcoxon test?

(b) What was your conclusion from the t test in Exercise 8.2-10?
