5. A chemist is interested in determining the weight loss y of a particular compound as a function of the amount of time the compound is exposed to the air. The data in the table give the weight losses associated with n = 12 settings of the independent variable, exposure time. Weight Loss (pounds) |Exposure Time (hours) 4.3 4 5.5 5 6.8 6 8.0 7 4.0 4 5.2 5 6.6 6 7.5 7 2.0 4 4.0 5 5.7 6 6.5 7 a. Make a GOOD graphic of the data. b. What is the correlation between exposure time and weight loss? c. Write and interpret the regression model. d. How accurately can we predict weight loss, given exposure time
