(choose chapter or problem)

The accompanying data show rounded mean values for blood alcohol concentration (BAC) for people of different weights, according to how many drinks (5 oz wine, 1.25 oz 80-proof liquor, or 12 oz beer) they have consumed. a. Examine the data on BAC for a 100-pound person. Are the data linear? If so, find a formula to express blood alcohol concentration, A, as a function of the number of drinks, D, for a 100-pound person. Blood Alcohol Concentration for Selected Weights Number of Drinks 100 lb 140 lb 180 lb 2 0.075 0.054 0.042 4 0.150 0.107 0.083 6 0.225 0.161 0.125 8 0.300 0.214 0.167 10 0.375 0.268 0.208 b. Examine the data on BAC for a 140-pound person. Are the data linear? If theyre not precisely linear, what might be a reasonable estimate for the average rate of change of blood alcohol concentration, A, with respect to number of drinks, D? Find a formula to estimate blood alcohol concentration, A, as a function of number of drinks, D, for a 140-pound person. Can you make any general conclusions about BAC as a function of number of drinks for all of the weight categories? c. Examine the data on BAC for people who consume two drinks. Are the data linear? If so, find a formula to express blood alcohol concentration, A, as a function of weight, W, for people who consume two drinks. Can you make any general conclusions about BAC as a function of weight for any particular number of drinks?
