And here is the question:

CASES A. Century National BankRefer to the description of Century National Bank on page 129 at the end of the Review of Chapters 1-4. With many other options available, customers no lon-ger let their money sit in a checking account. For many years the mean checking balance has been $1,600. Do the sample data indicate that the mean account balance has declined from this value? Recent years have also seen an increase in the use of ATM machines. When Mr. Selig took over the bank, the mean number of transactions per month per cus-tomer was 8; now he believes it has increased to more than 10. In fact, the advertising agency that prepares TV commercials for Century would like to use this on the new commercial being designed. Is there sufficient evidence to conclude that the mean number of transac-tions per customer is more than 10 per month? Could the advertising agency say the mean is more than 9 per month? The bank has branch offices in four different cities: Cincinnati, Ohio; Atlanta, Georgia; Louisville, Kentucky; and Erie, Pennsylvania. Mr. Selig would like to know whether there is a difference in the mean checking ac-count balances among the four branches. If there are dif-ferences, between which branches do these differences occur?d. If proper, test the other hypotheses at the .05 significance level. If it is not appropri-ate, describe why you should not do the tests. Mr. Selig is also interested in the bank's ATMs. Is there a difference in ATM use among the branches? Also, do customers who have debit cards tend to use ATMs differently from those who do not have debit cards? Is there a difference in ATM use by those with checking accounts that pay interest versus those that do not? Question is looking for a report for Mr. Selig answering these questions.

I am overwhelmed and don't know how to start breaking this down into steps to figure out how to answer. Are you able to assist with getting me started?
