A real estate company is interested in the ages of home buyers. They examined the ages of thousands of home buyers and found that the mean age was 45 years old, with a standard deviation of 9 years. Suppose that these measures are valid for the population of all home buyers. Complete the following statements about the distribution of all ages of home buyers.(b) According to Chebyshev's theorem, at least (Choose one) home buyers' ages lie between 31.5 years and 58.5 years.
