what sample size is needed for a 99% confidence interval and .025% margin error

#1
As a manufacturer of golf equipment, the Spaulding Corp. wants to estimate the proportion of golfers who are left handed. (The company can use this information in planning for the number of right handed and left handed sets of clubs to make) How many golfers must be surveyed if we want 99% confidence that the sample proportion has a margin of error of 0.025?
