Is there any help or thoughts on a question involving p-values

A sample of 64 account balances from a credit company showed an average daily balance of $1,045.The standard deviation of the population is known to be $240.We are interested in determining if the mean of all account balances (i.e., population mean) is significantly different from $1,000.

Question: Using the p-value approach at 95% confidence, test the above hypotheses.
