Chapter 1.3, Problem 11P
Critical Thinking An agricultural study is comparing the harvest volume of two types of barley. The site for the experiment is bordered by a river. The field is divided into eight plots of approximately the same size. The experiment calls for the plots to be blocked into four plots per Mock. Then, two plots of each block will be randomly assigned to one of the two barley types.
Two blocking schemes are shown below, with one Mock indicated by the white region and the other by the gray region. Which Mocking scheme. A or B. would be better? Explain.

6. Show that
I(AUB) = max{1{A}, I{B}} = I{A} + I{B} - I{A} I{B};
I(AB)= min{I{A}, I{B}} = I{A} I{B};
I{A A B} = I{A} + I{B}-21{A} I{B} = (I{A} - I{B})².
