In 2009 Noodles & Company introduced spaghetti and meatballs
to their menu. Before putting it on the menu, they performed taste
tests to determine the best-tasting spaghetti sauce. In a paired
comparison, 70 tasters were asked to rate their satisfaction with
two different sauces on a scale of 1–10 with 10 being the highest.
The mean difference in ratings was:
d=–0.385714 with a standard deviation of sd
= 1.37570. Use α = 0.05.

portfolio A has significantly greater variance in rates of
return than portfolio B? (b) At α = .025, is
there a significant difference in the means?
