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#)
