Based on a Random Sample of 25 Units of Product $\alpha$

question 104

True/False

Based on a random sample of 25 units of product X,the average weight is 102 lbs. ,and the sample standard deviation is 10 lbs.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 lbs.Assume the population is normally distributed.At $\alpha$ = .05,we fail to reject H₀.
