QuestionCompute the $z$-scores for Stephan's electric bills of \$83 (IL) and \$102 (FL) using their state means and standard deviations.

Studdy Solution
Calculate the z-score for Stephan's Florida electric bill$$z_{FL} = -0.750$$The z-scores for Stephan's Illinois and Florida electric bills are -0.625 and -0.750, respectively. This means that Stephan's electric bill in Illinois is0.625 standard deviations below the mean, and his electric bill in Florida is0.750 standard deviations below the mean. Therefore, relative to the distribution of electric bills in each state, Stephan's electric bill is less expensive in both states, but it is relatively more expensive in Illinois than in Florida.
