Use the excel file Final_Exam.xlsx, sheet "Regression," to answer this question. Insurance companies are known to charge different insurance rates for different categories of the population, such as the age of the insured. The table in the excel file shows the average insurance cost (premium) and the average insurance claim grouped by age in the second and third columns. If we use the "avg prem" to predict "avg claim" using simple linear regression, what is the R-square? Round the number to 3 decimal places. (For example, we round 0.1236~0.124) Show your work in the file (generate the output sheet using the "regression" data analysis tool). Otherwise, O points.
