\fA data set contains the following seven values. 6 2 4 9 1 3 5 (Round the intermediate values to 4 decimal places.) a. Find the range. b. Find the mean absolute deviation. (Round your answer to 4 decimal places.) c. Find the population variance. (Round your answer to 4 decimal places.) d. Find the population standard deviation. (Round your answer to 4 decimal places.) e. Find the interquartile range. f. Find the z score for each value. (Round your answers to 2 decimal places) z score for 6 = z score for 2 = z score for 4 = z score for 9 = z score for 1 = z score for 3 = z score for 5 =X Your answer is incorrect. According to Chebyshev's theorem, at least what proportion of the data will be within u + ko for each value of k? a. k = 2 75 (Round your answer to 2 decimal places, e.g.,0.12.) b. k = 2.5 84 (Round your answer to 2 decimal places, e.g.,0.12.) c. k = 1.6 87 (Round your answer to 3 decimal places, e.g.,0.123.) d. k = 3.2 89.59 (Round your answer to 3 decimal places, e.g.,0.123.)A distribution of numbers is approximately bell shaped. If the mean of the numbers is 125 and the standard deviation is 12, a. between what two numbers would approximately 68% of the values fall? between and b. Between what two numbers would 95% of the values fall? between and c. Between what two values would 99.7% of the values fall? between and Your answer is partially correct. Some numbers are not normally distributed. If the mean of the numbers is 38 and the standard deviation is 6, what proportion of values would fall between 26 and 50? What proportion of values would fall between 14 and 62? Between what two values would 89% of the values fall? (Round your answers to 2 decimal places.) At least |:l % of the values will fall between 26 and 50. At least % of the values fall between 14 and 62. Between _ and at least 89% of the values fall. X Your answer is incorrect. Business Travel News reported that the average per diem total for a business traveler in Paris, France is $608. Suppose the shape of the distribution of the per diem costs of a business traveler to Paris is unknown, but that 51% of the per diem figures are between $576 and $640. What is the value of the standard deviation? (Round the intermediate values to 3 decimal places. Round your answers to 2 decimal places.) Standard deviation = 21.03\" X Youransweris incorrect. H Environmentalists are concerned about emissions of sulfur dioxide into the air. The average number of days per year in which sulfur dioxide levels exceed 150 milligrams per cubic meter in Milan, Italy, is 29' The number of days per year in which emission limits are exceeded is normally distributed with a standard deviation of 4.0 days. a. What percentage of the years would average between 21 and 37 days of excess emissions of sulfur dioxide? b. What percentage of the years would exceed 37 days? (Round your answer to 1 decimal place eg., 32) % c. What percentage of the years would exceed 41 days? (Round your answer to 2 decimal places ea, 3.23) 0.1350 % d. In what percentage of the years would there be fewer than 25 days with excess sulfur dioxide emissions? % X Your answer is incorrect. According to Chebyshev's theorem, at least what proportion of the data will be within u + ko for each value of k? a. k = 2 75.00% (Round your answer to 2 decimal places, e.g.,0.12.) b. k = 2.5 84.00% (Round your answer to 2 decimal places, e.g.,0.12.) c. k = 1.7 65.40% (Round your answer to 3 decimal places, e.g.,0.123.) d. k = 4.4 94.83% (Round your answer to 3 decimal places, e.g.,0.123.)
