Using the empirical rule, find each approximate percentage below.a. What is the approximate percentage of healthy adults with body temperatures within 2 standard deviations of themean, or between 97.08°F and 99.60°F?b. What is the approximate percentage of healthy adults with body temperatures between 96.45°F and 100.23°F?a. Approximately % of healthy adults in this group have body temperatures within 2 standard deviations of the mean, orbetween 97.08°F and 99.60°F.(Type an integer or a decimal. Do not round.)b.

Use z scores to compare the given values. In a recent awards ceremony, the age of the winner for best actor was 28 and the age of the winner for best actress was 44. For all best actors, the mean age is 42.3 years and the standard deviation is 8.4 years. For all best actresses, the mean age is 33.3 years and the standard deviation is 10.7 years. (All ages are determined at the time of the awards ceremony.) Relative to their genders, who had the more extreme age when winning the award, the actor or the actress? Explain. Since the z score for the actor is z = and the z score for the actress is z=, the had the more extreme age. (Round to two decimal places.)

Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 68 miles per hour, with a standard deviation of 3 miles per hour. Estimate the percent of vehicles whose speeds are between 65 miles per hour and 71 miles per hour. (Assume the data set has a bell-shaped distribution.) Approximately nothing% of vehicles travel between 65 miles per hour and 71 miles per hour.
