D Question 1 7 pts The table shows the concentration of theophylline, a common asthma drug, in the bloodstream, as a function of time after injection of a 300-my initial dose. It is claimed that this data set is consistent with an exponential decay model where C is the concentration and t is the time Time (hrs) Concentration mg/L 0 12.5 10.1 7.6 5 3.5 Use a calculator to make a scatterplot of the data, then find the exponential regression function for the given data The values for a and b rounded to three decimal places are a= 12.896 b= 0.821 D Question 2 3 pts Use the exponential regression equation you found in question 1 to determine the concentration level in the blood stream after 20 hrs. Round the answer to 2 decimal places, and do not include the units which are in mg
