Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15. 102 128 The area of the shaded region is 0.4160 . (Round to four decimal places as needed.)The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.170F and a standard deviation of 0.650F. Using the empirical rule; find each approximate percentage below. a. What is the approximate percentage of healthy adults with body temperatures within 'l standard deviation of the mean: or between 9?.52F and 98.82F? b. What is the approximate percentage of healthy adults with body temperatures between QBBYUF and 99.47%\"? a. Approximately Dish of healthy adults in this group have body temperatures within 1 standard deviation of the mean; or between QT.52F and 98.82%. [Type an integer or a decimal. Do not round.) [3. Approximately We of healthy adults in this group have body temperatures between 96.8?03 and 99.4?F. [Type an integer or a decimal. Do not round.)
