Develop two test type questions open ended not multiple choi

Develop two test type questions (open ended not multiple choice) using either the Empirical Rule or Chebyshev\'s Theorem. Then post how to solve them.

Please show work.

Examples:

The median income of all Americans in 2010 is $33,810 with a standard deviation of $5,100. Use Chebyshev\'s Theorem to find an interval in which at least 75% of the Americans median income will lie?

The sample mean of monthly car payments in New York is $500 with a standard deviation of $50. What percent of car payments falls between $400 and $600?
