Consumers Energy states that the average electric bill across the state is $48.287. You want to test the claim that the average bill amount is actually less than $48.287. The hypotheses for this situation are as follows: Null Hypothesis: μ ≥ 48.287, Alternative Hypothesis: μ < 48.287. A random sample of 35 customer's bills shows an average cost of $51.651 with a standard deviation of $8.3447. What is the test statistic and p-value for this test?

Consumers Energy states that the average electric bill across the state is $147.49. You want to test the claim that the average bill amount is actually less than $147.49. The hypotheses for this situation are as follows: Null Hypothesis: μ ≥ 147.49, Alternative Hypothesis: μ < 147.49. You complete a randomized survey throughout the state and perform a one-sample hypothesis test for the mean, which results in a p-value of 0.0416. What is the appropriate conclusion? Conclude at the 5%...

Homeowners across the nation are concerned with how much their electric bill is each month. The American Housing Survey collects that information along with a whole host of other variables including the number of bedrooms in a house. Can the number of bedrooms in a house help us predict the electric bill? Twenty randomly selected houses produced the key numeric measures below where x = number of bedrooms and y = amount of electric bill in dollars. n=20 Σx =...

The makers of a soft drink want to identify the average age of its consumers. A sample of 55 consumers was taken. The average age in the sample was 21 years with a standard deviation of 4 years. a. Construct a 95% confidence interval for the true average age of the consumers. b. Construct an 80% confidence interval for the true average age of the consumers. c. Discuss why the 95% and 80% confidence intervals are different.
