The extract of a plant native to Taiwan has been tested as a possible treatment for Leukemia. One of the chemical compounds produced from the plant was analyzed for a particular collagen. The collagen amount was found to be normally distributed with a mean of 6161 and standard deviation of 5.95.9 grams per mililiter. (a)  What is the probability that the amount of collagen is greater than 6060 grams per mililiter? answer:  (b)  What is the probability that the amount of collagen is less than 7777 grams per mililiter? answer:  (c)  What percentage of compounds formed from the extract of this plant fall within 22 standard deviations of the mean? answer:  %
