The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.18"F and a standard deviation of 0.45 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 96.83"F and 99.53 F? b. What is the approximate percentage of healthy adults with body temperatures between 97.73"F and 98.63"F? a. Approximately % of healthy adults in this group have body temperatures within 3 standard deviations of the mean, or between 96.83"F and 99.53"F. (Type an integer or a decimal. Do not round.) b. Approximately |% of healthy adults in this group have body temperatures between 97.73"F and 98.63"F. (Type an integer or a decimal. Do not round.)Households are randomly selected and partitioned into groups of four. For those groups, the Plant} |=| random variable x is the number of households with a printer. Determine whether a probability [1.025 distribution is given. It a probability distribution is given, nd its mean and standard deviation. If a [1,143 probability distribution is not given, identity the requirements that are not satisfied. {3.343 [1.354 [1.135 Does the table show a probability distribution? Select all that apply. |:I A. Yes, the table shows a probability distribution. |:I E. No. not every probability is between CI and 1 inclusive. |:I C. No. the random variable x is categorical instead of numerical. |:I D. No. the numerical values of the random variable x are not associated with probabilities. |:I E. No. the sum of all the probabilities is not equal to 1. Find the mean of the random variable x.
