The amount of chocolate is then weighed. Each container should contain 4 ounces of chocolate. The results of a simple random sample of 12 containers is shown below. Assume the amount of chocolate added to the ice cream is normally distributed. Chocolate Mean 3.917 Variance 0.042 Observations 12 Hypothesized Mean What condition is met for the use of a t-distribution? of 11 t Stat -1.42 Pick P(T<=t) one-tail 0.092 t Critical one-tail 2.718 What is the level of significance?
