A candy bar manufacturer sells a "fun size" version that is advertised to weigh 17 grams. A hungry teacher selected a random sample of 44 fun size bars and found a 95% confidence interval for the true mean weight to be 16.945 grams to 17.395 grams Does the confidence interval provide convincing evidence that the true mean weight is 17 grams? Explain your answer. Yes. Because the 95% confidence interval contains the value 17, there is convincing evidence that the true mean weigh is 17 grams. We are 95% confident that the interval from 16.945 to 17.395 contains the true mean weight of fun size candy bars.
