Question

Let X equal the weight in grams of a “52-gram” snack pack of candies. Assume that the distribution of X is N(μ, 4). A random sample of n = 10 observations of X yielded the following data:
(a) Give a point estimate for μ.
(b) Find the endpoints for a 95% confidence interval for μ.
(c) On the basis of these very limited data, what is the probability that an individual snack pack selected at random is filled with less than 52 grams of candy?
