Question: The weight of many manufactured items is approximately normally distributed. For new U.S. pennies, the mean is 3.11 grams and the standard deviation is 0.05 gram (Youden, 1962).
a. What proportion of all new pennies would you expect to weigh more than 3.20 grams?
b. What weights separate the middle 80 percent of the pennies from the lightest 10 percent and the heaviest 10 percent?
Proportional to xi2, that is Var(εi)=σ2 xi2. Suppose that we use the transformation y'=y/x and x'=1/x. Is this a variance-stabilizing transformation?

Let z be a standard normal random variable and calculate the following probabilities:
Jim has weighted GPA of 3.84. His high school GPA's are normally distributed with a mean of 2.9 and a standard deviation of 0.5. Kim's high school uses unweighted GPA's and she has a GPA of 3.57. GPA's are also normally distributed in her high sch..
