The article Improving Fermentation Productivity with Reverse Osmosis (Food Technology [1984]: 9296) gave the following data (read from a scatterplot) on y glucose concentration (g/L) and x fermentation time (days) for a blend of malt liquor. x 12345678 y 74 54 52 51 52 53 58 71 a. Use the data to calculate the estimated regression line. b. Do the data indicate a linear relationship between y and x? Test using a .10 significance level. c. Using the estimated regression line of Part (a), compute the residuals and construct a plot of the residuals versus x (that is, of the (x, residual) pairs). d. Based on the plot in Part (c), do you think that a linear model is appropriate for describing the relationship between y and x? Explain.
