Chebyshev's Theorem states that for any distribution of numerical data, at least 1-1/k? of the numbers lie within The percent of numbers between 88 and 112 is at least %. k standard deviations of the mean. (Round to the nearest hundredth as needed.) In a certain distribution of numbers, the mean is 100, with a standard deviation of 6. Use Chebyshev's Theorem to tell what percent of the numbers are between 88 and 112.

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 46 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.80 ml/kg for the distribution of blood plasma. When finding an 99% confidence interval, what is the critical value for confidence level?

The weights in pounds of a breed of yearling cattle follows the Normal model N(1157,77). What weight would be considered unusually low for such an animal? Select the correct choice below and fill in the answer boxes within your choice. O A. Any weight more than 2 standard deviations below the mean, or less than pounds, is unusually low. One would expect to see a steer 3 standard deviations below the mean, or less than pounds only rarely. O B. Any weight more than 3 standard deviations below the mean, or less than pounds, is unusually low. One would expect to see a steer standard deviations below the mean, or less than pounds only rarely. O C. Any weight more than 1 standard deviation below the mean, or less than pounds, is unusually low. One would expect to see a steer 2 standard deviations below the mean, or less than pounds only rarely.
