I want to see if there is a relation between makeup sales andthe age of people buying them on any given day at Sephora. 10people were randomly sampled.
X-axis: 13, 14, 16, 17, 21, 25, 30, 37, 50, 62 (age)
Y-axis: 2, 7, 30, 26, 15, 33, 7, 3, 14, 1 (Makeup sales)
What is the impact of using a linear regression model in thiscase? What options, other than linear regression, can you see? Youdo not need to collect any data.
For your response to a classmate (two responses required, one ineach option), examine your classmate’s problem to assess theappropriateness and accuracy of using a linear regression model.Discuss the meaning of the standard error of the estimate and howit affects the predicted values of Y for that analysis.
