Problem 5: 17 points) Let X equal the weight in grams of a 52-gram snack pack of candies. Assume that the distribution of X is N(2,0?). A random sample of n = 10 observations of X yield the following data: 55.95, 56.54, 57,58, 55.13, 57.48, 56.06, 59.93, 58.3, 52.57, 58.46. (a) Give a point estimate of and a based on the data. [3] (b) Find the endpoints of a 95% confidence interval for . (2) (e) Suppose now that X...
