The ages of a sample of Canadian tourists flying from Toronto to Hong Kong were: 59, 71, 57, 50, 80, 49, 45, 61, 53, and 45. a. Compute the range. Range b. Compute the mean deviation. (Round the mean deviation to 2 decimal places.) Mean deviation c. Compute the standard deviation. (Round the standard deviation to 2 decimal places.) Standard deviation d. Using Chebyshev's theorem, at least what percentage of the observations must be within 1.3 standard deviations of the mean? (Round the final answer to the nearest whole number.) Percent of the observations e. Using the Empirical Rule, about 95% of the values would occur between what values? (Round the final answers to 2 decimal places.) Between and
