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 peso) and degree of customer satisfaction (on a scale of 10 - 100 with a 10 being not at all satisfied and a 100 being extremely satisfied). The researcher only includes programs with comparable types of services. A sample of the data is provided below. Satisfaction Pesos 550 54 900 87 850 66 750 73 450 59 250 77 600 70 950 99 1100 95 1250 88 a. Compute for the correlation coefficient. Ans = Blank 1 b. Compute for the coefficient of determination. Ans = Blank 2 c. Determine the Regression Equation. y = Blank 3 + Blank 4 x
