Construct the confidence interval for Exercise assuming that s is known to be 2.55 chocolate chips. Find the confidence interval using the known value of S.
Answer to relevant QuestionsIf the first value of 3.0 in Exercise 21 is changed to 300, it becomes an outlier. Does this outlier have much of an effect on the confidence interval?
