- Suppose that the manager of a paint store wants to estimate the actual amount of paint contained in all 1- gallon cans of Acme Paint. She takes a random sample of 50 cans from the stockroom and finds the average amount of paint per can is .995 g with a S.D. of .02 g. Construct a 95% interval estimate for the true mean amount of paint in all 1-gal cans.

- A boat capsized and sank in a lake. Based on an assumption of a mean weight of 130 lb, the boat was rated to carry 70 passengers (so the load limit was 9,100 lb). After the boat sank, the assumed mean weight for similar boats was changed from 130 lb to 175 lb. Complete parts a and b below. a. Assume that a similar boat is loaded with 70 passengers, and assume that the weights of people are normally distributed with a mean of 180.7 Ib and a standard deviation of 35.5 lb. Find the probability that the boat is overloaded because the 70 passengers have a mean weight greater than 130 lb. The probability is 1. (Round to four decimal places as needed.) b. The boat was later rated to carry only 15 passengers, and the load limit was changed to 2,625 lb. Find the probability that the boat is overloaded because the mean weight of the passengers is greater than 175 (so that their total weight is greater than the maximum capacity of 2,625 lb). The probability is (Round to four decimal places as…Determine whether the given value is from a discrete or continuous data set.
