Pinworm: In a prior sample of U. S. adults, the Center for Disease Control (CDC), found that 10% of the people in this sample had pinworm but the margin of error for the population estimate was too large. They want an estimate that is in error by no more than 2.5 percentage points at the 95% confidence level. Enter your answers as whole numbers.
