A local utility company claims that the monthly electricity bills of its customers are among the lowest in the state with an average monthly electricity bill of $95.98. An energy analyst believes that the average monthly electricity bill from this utility company is actually higher than S95.98. The analyst collected a random sample of 39 monthly electricity bills from this utility company and found that the average monthly bill of the sample was $105.58, with a standard deviation of $16.90. Use the critical-value method to test the hypothesis that the average monthly electricity bill for customers of this local utility is greater than $95.98, using a = 0.1. State the null and alternative hypothesis for this test. O Ho: µ > 95.98, H1: µ = 95.98 O Ho:µ = 95.98, H1:u> 95.98 O Ho: µ = 95.98, H1: p 95.98 O Ho: µ = 95.98, H1: µ < 95.98 Determine the critical-value for the hypothesis test. O 3.5657 O1.6859 O 2.0244 O1.3042 Determine the test statistic for the hypothesis test. O 2.7424 O 0.5681 O 3.9324 O 3.5479

03.5479 Determine the appropriate conclusion for this hypothesis test. O The sample data do not provide sufficient evidence to reject the alternative hypothesis that the average monthly electricity bill from this utility company is greater than $95.98 and thus we conclude that the average monthly electricity bill from this utility company is likely greater than $95.98. O The sample data do not provide sufficient evidence to reject the null hypothesis that the average monthly electricity bill from this utility company is $95.98 and thus we conclude that average monthly electricity bill from this utility company is likely about $95.98. O The sample data provide sufficient evidence to reject the alternative hypothesis that the average monthly electricity bill from this utility company is greater than $95.98 and thus we conclude that the average monthly electricity bill from this utility company is likely about $95.98, as claimed. O The sample data provide sufficient evidence to reject the null hypothesis that the average monthly electricity bill from this utility company is $95.98 and thus we conclude that average monthly electricity bill from this utility company is likely greater than $95.98. > Next Question
