The state education commission wants to estimate the proportion of tenth-grade students in the state who read at or below the eight-grade level. The commissioner wants an estimate with a 99% level of confidence and an error of at most 5%?   Step 1 of 2:  Assuming the commissioner has no prior knowledge about the proportion, how large of a sample would be required for the commissioner to make the desired estimate? Round your answer up to the next integer.
