Cost and Customer Satisfaction A researcher is interested whether there is a linear correlation between cost (in dollars) of internet service per month and customer satisfaction on a scale of 1 - 10 (with a 1 being extremely dissatisfied and 10 extremely satisfied). The researcher only includes internet service with similar download speed. The sample he collected is below. Cost (x) 15 18 17 11 9 11 12 19 18 22 Satisfaction (y) 6 8 10 4 9 6 3 5 2 10 Find the regression equation.
