Multiple Choice

Recently, Experian reported that the average credit score for a new- car loan was 753. Suppose Ally Financial, a bank holding company that finances car loans, would like to test the hypothesis that the average credit score has increased since the Experian report. A random sample of 20 new- car loans had an average credit score of 764.2 with a sample standard deviation of 34.5. Ally Financial would like to set α = 0.05. The conclusion for this hypothesis test would be that because the test statistic is _________.

A) less than the critical value, we cannot conclude that the average credit score for a new- car loan is not more than 753
B) more than the critical value, we cannot conclude that the average credit score for a new- car loan is not more than 753
C) more than the critical value, we can conclude that the average credit score for a new- car loan is more than 753
D) less than the critical value, we can conclude that the average credit score for a new- car loan is more than 753
