The ages of a sample of Canadian tourists flying from Toronto to Hong Kong were 30,42,34,52,61,46,39,55,76, and 72 . 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 stondard deviation to 2 decimal ploces.) Standard deviation d. Using Chebyshev's theorem, at least what percentage of the observations must be within 2.3 standard devabomi of the mean? (Round the finol 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 onswers to 2 decimal ploces.) Between and
