Scientists conduct a pilot study of 153 people exposed to a biohazard and find that 32 of them test positive for infection. They want to create a 98% confidence interval to estimate the proportion of all people exposed to this biohazard who will likely develop infection. The margin of error in their confidence interval was 0.076. If they want to cut the error in half, how many people must they inspect?
