Question

Consumers Energy states that the average electric bill across the state is $67.16. You want to test the claim that the average bill amount is greater than $67.16. The hypotheses for this situation are Null Hypothesis: u = 67.16, Alternative Hypothesis: u > 67.16. If the true statewide average bill is $51.28 and the null hypothesis is not rejected, did a type I, type II, or no error occur? No error has occurred. Type I Error has occurred. Type II Error has occurred. We do not know the p-value, so we cannot determine if an error has occurred.

No error has occurred.
Type I Error has occurred.
Type II Error has occurred.
