A bank found that in recent years, the average monthly charge on its credit card was $1,450. With an improving economy, they $183.37. Do these data provide statistical evidence that the average monthly charge has increased? Formulate the appropriate Is there sufficient evidence at the 0.05 level of significance that the average monthly charge has increased? Determine the null hypothesis, Ho, and the alternative hypothesis, H, H₂S 1450 H,> 1450 (Type whole numbers.) Compute the test statistic 0.90 (Round to two decimal places as needed) Using a level of significance of 0.05, what is the critical value? 1.68 (Round to two decimal places as needed.) Find the p-value for the test. (Round to three decimal places as needed) suspect that this amount has increased A sample of 40 customers resulted in an average monthly charge of $1,476.19 with a standard deviation of hypothesis test and draw a conclusion. Use a level of significance of 0.05 G
