Unformatted text preview: F > F α /2 ( n Y – 1, n X – 1). So for (a) and (b), F depends on H 1 , whichever is larger shall put into the numerator. (c) For H 1 : σ X 2 ≠ σ Y 2 , F = larger sample variance/smaller sample variance, the rejection rule is F > F α /2 ( n larger sample variance – 1, n smaller sample variance – 1) or F < F 1α /2 ( n larger sample variance – 1, n smaller sample variance – 1). Essentially, only the first part is possible. Taylor 8 April 2009...
