The weight of a miniature Tootsie Roll is normally distributed with a mean of 3.30 grams and standard deviation of 0.13 gram.
(a) Within what weight range will the middle 95 percent of all miniature Tootsie Rolls fall? Hint: Use the Empirical rule.
(b) What is the probability that a randomly chosen miniature Tootsie Roll will weigh more than 3.50 grams? (Data are from a project by MBA student Henry Scussel.)
