Cora wants to determine a 99 percent confidence interval for the true proportion p of high school students in the area who attend their home basketball games. Out of n randomly selected students she finds that that exactly half attend their home basketball games. About how large wouldn have to be to get a margin of error less than 0.01 for p? [Use the values for z* from a z- table or t-table, and round to the smallest integer that works.] na
