A clinic took temperature readings of 250 flu patients over a weekend and discovered the temperature distribution to be Gaussian, with a mean of 101.30°F and a standard deviation of 0.8490. Use this normal error curve area table to find the following values. (a) What is the fraction of patients expected to have a fever greater than 103.68°F?(b) What is the fraction of patients expected to have a temperature between 100.79°F and 102.06°F?
