. The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth-grade level. In an earlier study, the population proportion was estimated to be 0.23. How large a sample would be required in order to estimate the fraction of tenth graders reading at or below the eighth-grade level at the 98% confidence level with an error of at most 0.02? Round your answer up to the next integer.
