Based on a Random Sample of 25 Units of Product

question 33

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 whether 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 value of the test statistic to test the claim?
