Most people think that the "normal" adult body temperature is 98.6F. In a more recent study, researchers reported that a more accurate figure may be 98.1F. Furthermore, the standard deviation appeared to be around 0.8F. Assume that a Normal model is appropriate. Complete parts a through c below. a) In what interval would you expect most people's body temperatures to be? Explain. Select the correct choice below and fill in the answer box(es) to complete your choice. A. Using the 68-95-99.7 Rule, about 95% of the body temperatures are expected to be between 96.5 F and 99.7 F. (Use ascending order. Round to one decimal place as needed.) OB. Using the 68-95-99.7 Rule, about 95% of the body temperatures are expected to be less than (Round to one decimal place as needed.) F. OC. Using the 68-95-99.7 Rule, about 95% of the body temperatures are expected to be at least (Round to one decimal place as needed.) F b) What fraction of people would be expected to have body temperatures above 98.6F? % (Round to two decimal places as needed.)
