The Owners of an Industrial Plant Want to Determine Which $H _ { 0 } : \left( \mu _ { e } - \mu _ { g } \right) = 0$

question 49

Multiple Choice

The owners of an industrial plant want to determine which of two types of fuel (gas or electricity) will produce more useful energy at a lower cost. The cost is measured by plant investment per
Delivered quad ($ invested /quadrillion BTUs) . The smaller this number, the less the industrial
Plant pays for delivered energy. Suppose we wish to determine if there is a difference in the
Average investment/quad between using electricity and using gas. Our null and alternative
Hypotheses would be:

• A) \(H _ { 0 } : \left( \mu _ { e } - \mu _ { g } \right) = 0\) vs. \(H _ { a } : \left( \mu _ { e } - \mu _ { g } \right) \neq 0\)
• B) \(H _ { 0 } : \left( \mu _ { e } - \mu _ { g } \right) = 0\) vs. \(H _ { a } : \left( \mu _ { e } - \mu _ { g } \right) < 0\)
• C) \(H _ { 0 } : \left( \mu _ { e } - \mu _ { g } \right) = 0\) vs. \(H _ { a } : \left( \mu _ { e } - \mu _ { g } \right) > 0\)
• D) \(H _ { 0 } : \left( \mu _ { e } - \mu _ { g } \right) = 0\) vs. \(H _ { a } : \left( \mu _ { e } - \mu _ { g } \right) = 0\)
