(1 point) Dylan wants to determine a 99 percent confidence interval for the true proportion of high school students in the area who attend their home basketball games. How large of a sample must he have to get a margin of error less than 0.02? [To find n, use the value p* = 1/2 for the sample proportion and the values for z* from a z-table or t-table.] [Round to the smallest integer that works.] n =
