A candy bar manufacturer sells a "fun size" version that is advertised to weigh 17 grams. A hungry teacher selected a randomsample 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 weightis 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.Because the point estimate is 17.17 grams, there is not convincing evidence that the true mean weight is 17 grams.No. Although 17 is a plausible value for the true mean weight of all cans of diet cola, there are many other plausiblevalues besides 17 in the confidence interval. Because any of these values could be the true mean, there is notconvincing evidence that the true mean weight is 17 grams.Even though this confidence interval includes 17 grams, this might not occur again in different samples. There is notenough evidence to make a conclusion regarding the true mean weight.We are 95% confident that the interval from 16.945 to 17.395 contains the true mean weight of fun size candy bars.Because we are not 100% certain, there is not convincing evidence that the true mean weight is equal to 17 grams.
