In R Studio data set link https://college.cengage.com/mathematics/brase/understandable_statistics/7e/students/datasets/mlr/frames/mlr06.html

The data (X1, X2, X3, X4, X5, X6, X7) are for each city. X1 = total overall reported crime rate per 1 million residents X2 = reported violent crime rate per 100,000 residents X3 = annual police funding in $/resident X4 = % of people 25 years+ with 4 yrs. of high school X5 = % of 16 to 19 year-olds not in high school and not high school graduates. X6 = % of 18 to 24 year-olds in college X7 = % of people 25 years+ with at least 4 years of college Investigate whether there is coorelation between X3 and X2, What is pearson coorelation coefcient, How do you interpret it. Does a linear relationship exist between X3 and X2 ? What about X3 and X1 ? How can you determine that definitvely? Hint: residuals
