With the growth of internet service providers, a researcher decides to examine whether there is a correlation between cost of internet service per month 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. a. Compute the correlation coefficient. b. What percent of the variability is accounted for by the relationship between the two variables and what does this statistic mean? Refer to problem #4 and answer the following: a. Determine the least-square prediction line and plot the graph. b. Test for the significance of the regression coefficient (value of b) at 2% level of significance and interpret the results. c. Construct an ANOVA Table for the linear regression
