Problem 4 A sample of 15 small bags of the same brand of candies was selected. Assume that the population distribution of bag weights is normal. The weight of each bag was then recorded. The mean weight was 2 ounces with a sample standard deviations 0.2 ounces. We would like to calculate an 80% confidence interval for the average weight of a sample of size 15 . a. (3%) standard error- b. (396) The critical t value for an 80%...

A sample of 14 small bags of the same brand of candies was selected. Assume that the population distribution of bag weights is normal. The weight of each bag was then recorded. The mean weight was 3 ounces with a standard deviation of 0.15 ounces. The population standard deviation is known to be 0.1 ounce. NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed. (In general, you must first prove that...

3. Fun size M&Ms candies contain between 15 and 18 candies and uniformly distributed among bags. Sup- pose a sample of 30 bags is chosen from a large Costco size bag of Fun Size M&Ms. a) What is the population mean and standard deviation? Hint: bag size is given to us as uniformly distributed b) What is the probability that the mean number of candies in 30 bags is less than 15 candies? c) What is the probability that the...
