A study was made on the amount of converted sugar in a certain process at various temperatures. The data were coded and recorded as follows: Temperature 1.0 1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 2.0 Conv. Sugar 8.1 7.8 8.5 9.8 9.5 8.9 8.6 10.2 9.3 9.2 10.5 A. Which is the predictor variable and the response variable? B. Compute Pearson sample correlation coefficient r and interpret its nature and magnitude. C. Compute the sample coefficient of determination and interpret.
