Is this asking for the confidence interval? If so, how to calculate?

A company that produces universal remote controls wanted to determine the number of remote control devices American homes contain. The company hired a statistician to survey 240 randomly selected homes and determine the number of remote controls. If there are 100 million households, estimate with 99% confidence the total number of remote controls in the United States. (Given data: sample mean=4.6625 and sample deviation=2.367548)
