Consumers Energy states that the average electric bill across the state is $34.431. You want to test the claim that the average bill amount is actually different from $34.431. The hypotheses for this situation are as follows: Null Hypothesis: μ = 34.431, Alternative Hypothesis: μ ≠ 34.431. A random sample of 38 customer's bills shows an average cost of $34.35 with a standard deviation of $6.6195. What is the test statistic and p-value for this test?
