A sample of assistant professors on the business faculty at state supported institutions in Ohio revealed the mean income to be $32,000 for 9 months with a standard deviation of $3,000. Using Chebyshev's Theorem, what is the proportion of faculty that earn more than $26,000 but less than $38,000?

David's gasoline station offers 4 cents off per gallon if the customer pays in cash and does not use a credit card. Past evidence indicates that 40% of all customers pay in cash. During a one hour period twenty-five customers buy gasoline at this station. What is the probability that no more than twenty pay in cash?

  1. 0.1
  2. 0.9
  3. None of these answers
  4. 0.0
  5. 1.0

Answer(s): E

Explanation:

P(20) is almost zero. Probabilities of higher than 20 are also close to zero. So the probability of not more than 20 is almost 1.
