In 1997, the average household expenditure for energy was $1,338, according to data obtained from the U. S. Department of Energy. An economist claims that energy usage today is different from its 1997 level. In a random sample of 36 households, the economist found the mean expenditure, adjusted for inflation, for energy in 2004 to be $1,423. with a sample standard deviation s = 360.
At a 95% level of confidence (α = .05), we wish to test the economists claim. State the Null Hypothesis and Alternate Hypothesis for this experiment.
