The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.17% and a standard deviation of 0.55%. Using the empirical rule; find each approximate percentage below. a. What is the approximate percentage of healthy adults with body temperatures within 1 standard deviation of the mean: or between 9?.52% and 98.82%? b. What is the approximate percentage of healthy adults with body temperatures between 95.8?% and 99.47%? a. Approximately DEE-t: of healthy adults in this group have body temperatures within 1 standard deviation of the mean; or between 97.52% and 98.82%. (Type an integer or a decimal. Do not round.) b. Approximately |:|% of healthy adults in this group have body temperatures between 96.8?% and 99.4?%. (Type an integer or a decimal. Do not round.) A data set lists weights (Ib) of plastic discarded by households. The highest weight is 5.13 lb, the mean of all of the weights is x = 2.136 lb, and the standard deviation of the weights is s = 1.025 lb. a. What is the difference between the weight of 5.13 lb and the mean of the weights? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the weight of 5.13 lb to a z score. d. If we consider weights that convert to z scores between - 2 and 2 to be neither significantly low nor significantly high, is the weight of 5.13 lb significant? a. The difference is (Type an integer or a decimal. Do not round.) b. The difference is standard deviations. (Round to two decimal places as needed.) c. The z score is z = (Round to two decimal places as needed.) d. The highest weight is
