Question 1

The screen below shows the 95% confidence interval for



What does the interval suggest about the relationship between μ1 and μ2?

Question 2

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:
◦ H0: (μe - μg) = 0 vs. Ha: (μe - μg) ≠ 0
◦ H0: (μe - μg) = 0 vs. Ha: (μe - μg) = 0
◦ H0: (μe - μg) = 0 vs. Ha: (μe - μg) > 0
◦ H0: (μe - μg) = 0 vs. Ha: (μe - μg) < 0
