For the lettuce yield data, (page 494) it is thought that the yields from fertilizer A might have a larger variance than the yields from fertilizer B.
a. Compute the sample variances s^ and s2B of the yields assigned to and , respectively, and the quotient .
b. Someone suggests using the F test in Section 6.11 for this problem. Is this a good idea? Why or why not?
c. Perform a randomization test of H0: versus H1: using the test statistic , and a minimum of 1000 random outcomes.
(Hint: Proceed just as in the example in the text, but for each outcome compute ,and rather than and . A fair amount of coding may be required, depending on the software used.)
