If so, whether they paid their balance in full each month. There were 400 who did not pay balance in full each month.

Is there convincing evidence that college students who do not pay their credit card balance in full each month have a mean balance that is different than $820 at 0.02 level of significance? 3y) What is your conclusion based on the decisions under p-value, Critical-value, and Confidence Intervals approaches for this Hypothesis Test?
