Acpu manufacturer is interested in studying the relationship between clock speed and the operating temperature that results at that clock speed for a particular cpu model. let x be the clock speed in mhz and let y be the temperature in ^{\circ}c . the following data was collected: i xi yi1 350 31.42 360 35.63 370 41.84 380 51.05 390 56.86 400 62.87 410 67.4a) find the equation of the regression line. b) estimate the temperature for clock speed x = 430 mhz. c) find the 95% confidence interval for \beta .d) compute the coefficient of determination r^{2} ? . is this a high quality fit?
