The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.15°F and a standard deviation of 0.67°F. Using the empirical rule, find each approximate percentage below. a. What is the approximate percentage of healthy adults with body temperatures within 3 standard deviations of the mean, or between 96.14°F and 100.16°F? b. What is the approximate percentage of healthy adults with body temperatures between 96.81°F and 99.49°F? a. Approximately % of healthy adults in this group have body temperatures within 3 standard deviations of the mean, or between 96.14°F and 100.16°F. (Type an integer or a decimal. Do not round.) b. Approximately% of healthy adults in this group have body temperatures between 96.81°F and 99.49°F. (Type an integer or a decimal. Do not round.)

Below are the jersey numbers of 11 players randomly selected from a football team. Find the range, variance, and standard deviation for the given sample data. What do the results tell us? 91 6 63 60 81 15 94 18 8 19 86 O Range = (Round to one decimal place as needed.) Sample standard deviation (Round to one decimal place as needed.) Sample variance = | (Round to one decimal place as needed.) What do the results tell us? O A. The sample standard deviation is too large in comparison to the range. OB. Jersey numbers on a football team do not vary as much as expected. OC. Jersey numbers on a football team vary much more than expected. D. Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.
