2. With the growth of internet service providers, a researcher decides to examine whether there is a correlation between cost of internet service per month (rounded to the nearest dollar) and degree of customer satisfaction (on a scale of 1 - 10 with a 1 being not at all satisfied and a 10 being extremely satisfied). The researcher only includes programs with comparable types of services. A sample of the data is provided below. dollars satisfaction 11 6 18 8 17 10 15 4 9 5 6 12 3 19 22 2 25 10 a. Compute the correlation coefficient. b. Determine the equation of regression if the level of satisfaction is being predicted. c. What satisfaction level would the customers achieved if they are paying $20? $8? $16? d. Determine the equation of regression if the cost is being predicted. e. How much would it cost to have a satisfaction level of 7? f. Explain the predicting capability of the equation.
