10. (9 points, 3 points each) Consider the following set of data based on a sample of 5 people. For each person, the average number of times they work out each week (X) as well as their resting heart rate (Y) was recorded. Use this information to answer the following questions. Round all values to 3 decimal places, Person 1 2 3 4 5 X (Workouts per week) 4 3 5 7 2 Y (Heart Rate) 70 77 65 55 83 a. Find the value of Pearson's correlation coefficient for this data set. What does this value tell you about the relationship between these variables? b. Find the equation of the least squares regression line. c. If it is appropriate, use the regression line you found in part (b) to predict the resting heart rate for someone who works out an average of 6 times per week. If it is not appropriate, then justify why it is not
