Consider when businesses might use confidence intervals to estimate values, such asin sales projections, marketing results, and so forth. Describe a business decision thatcould be helped with confidence intervals. Be specific! Then create a problem withnumbers from which another student could calculate a confidence interval and make adecision.

MATH 534 Week 6 Discussion Regression Analysis Suppose you are given data from a survey showing the IQ of each person interviewed and the IQof his or her mother. That is all the information that you have. Your boss has asked you to puttogether a report showing the relationship between these two variables. What could you present,and why?
