A clinic took temperature readings of 250 flu patients over a weekend and discovered the temperature distribution to be Gaussian, with a mean of 101.00°F and a standard deviation of 0.6530. 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 102.70°F?
(b) What is the fraction of patients expected to have a temperature between 100.48°F and 101.98°F?
