Based on a Random Sample of 25 Units of Product

question 127

Short Answer

Based on a random sample of 25 units of product X, the average weight is 102 lb and the sample standard deviation is 10 lb. We would like to decide if there is enough evidence to establish that the average weight for the population of product X is greater than 100 lb. Assume the population is normally distributed. What is the critical value to test the claim at α = .01?
