The data from 157 bills are stored in Restaurant Tips and include the amount of the bill, size of the tip, percentage tip, number of customers in the group, whether or not a credit card was used, day of the week, and a coded identity of the server. We want to use the bill amount to predict the tip amount. A scatterplot of this relationship is shown below. 16 14- 12- 10 은 8 6- 4 2 0 .: 10 20 30 40 50 60 70 Bill (1) Describe the relationship between the bill amount and the tip amount at this restaurant. 0 (2) Estimate the correlation between these two variables.
