8. Data consists of sound levels {in dB} and sales price {in 5'; for dishwashers. For the paired data, do a complete regression analysis: [15 m5] 3} Draw a scatter plot graph for the data. b} Compute the value of the correlation coefficient. at Identify the Critical Value {CV} and determine if there is a signicant linear correlation. d} Determine the linear regression equation and plot the line Dl'l the scatter plot. e} What is the best predicted sales price for a dishwasher with a sound level of 49 dB {X = 491?
