Data summarized below show how the amount of a catalyst added to a reaction inuenced the extent of that reaction. Use these data to address the tasks below. d % reaction 1. Create a scatter diagram showing the extent of the reaction as a function of the amount of catalyst added. How many points appear in an almost parallel line below most of the data? What is the value of Sn? What is the value of Sxy? Based on the above values, what is your estimate of the slope for the regression model? What is the mean of the % added values? What is the mean of the % reaction values? Based on the above values, what is your estimate of the intercept? Based on the above values, what is the error sum of squares? 9. Based on the above values, what is your estimate of the variance of the error term? 10. Based on the above values, what is your estimate of the standard error of the SIOpe? 11. Based on the above values, what is your estimate of the standard error of the intercept? $749999!\" You can check many of the above answers using the command lm( )
