Extracted text: 1. The amounts of solids removed from a particular material when exposed to drying periods of different lengths are shown in the table below: Drying period (hours) Solids removed (grams) 4.4 13.1 4.4 14.2 4.5 9.0 4.5 11.5 4.8 10.4 4.8 11.5 5.5 13.8 5.5 14.8 5.7 12.7 5.7 15.1 5.9 9.9 5.9 12.7 6.3 13.8 6.3 16.5 6.9 16.4 6.9 15.7 7.5 17.6 7.5 16.9 7.8 18.3 7.8 17.2 a. Validate the claim that the drying period has influence on the amount of solids removed from a particular material by testing the linear correlation between the two variables. b. If there is a linear correlation, based on your computation in letter (a), construct a simple linear regression model. Otherwise, disregard this question and the next question. c. Estimate the amount of solids removed when drying period is 5.0 hours.
