The tallest living man at one time had a height of 252 cm. The shortest living man at that time had a height of 114.8 cm. Heights of men at that time had a mean of 176.59 cm and a standard deviation of 8.31 cm. Which of these two men had the height that was more extreme? Since the z score for the tallest man is z = D and the z score for the shortest man is z = D, the man had the height that was more extreme. (Round to two decimal places.) - tallest shortest Households are randomly selected and partitioned into groups of four. For those groups, the random variable x is the number of households with a printer. Determine whether a T P(x) El probability distribution is given. If a probability distribution is given, nd its mean and standard deviation. If a probability distribution is not given, identify the requirements that are 0 0.028 not satised. T 0.145 T 0.335 T 0.357 I 0.135 Does the table show a probability distribution? Select all that apply. V Yes, the table shows a probability distribution. No, the numerical values of the random variable x are not associated with probabilities. No, not every probability is between 0 and 1 inclusive. No, the sum of all the probabilities is not equal to 1. No, the random variable x is categorical instead of numerical. Find the mean of the random variable x. Select the correct choice below and, if necessary, ll in the answer box to complete your choice. A- p = household(s) (Round to one decimal place as needed.) (:3 B.
