A recent report shows that the cost of electricity for a single family home in neighborhood A was about $258 per month. The electric company believes a nearby neighborhood B has a higher per house cost. A researcher went to collect data, and the hypotheses are as follows: μ = 258
μ > 258
What is the type II error for this test?
a. Researcher cannot conclude the cost is higher in neighborhood B, but in fact it is higher.
b. Researcher cannot conclude the cost is higher in neighborhood B, and it is true.
c. Researcher concludes the cost is higher in neighborhood B, and it is true.
d. Researcher concludes the cost is higher in neighborhood B, but in fact it is not.
