The amounts of a chemical compound which dissolved in 100 grams of water at various temperatures were recorded as follows: Temperature Amount (°C) Dissolved (g) 8. 6. 8 15 12 15 10 15 14 30 25 30 21 30 24 45 31 45 33 45 28 60 44 60 39 60 42 75 48 75 51 75 44 а. Validate the claim that the amount of chemical compound dissolved in 100 grams of water is influenced by the temperature by testing the linear correlation of 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. С. Estimate the amount of chemical compound dissolved in 100 grams of water at 25°C.
