An official at the Emergency Operations Center of St. Lucie county needs to estimate the proportion of county residents that plan not to evacuate in the event of a hurricane. To help with this estimate, the official surveyed a small group of county residents and found that 88% of the sample do not plan to evacuate in the event of a hurricane. How large a sample should be selected such that the margin of error of the estimate for a 99% confidence interval is at most 7.8%. Round the solution up to the nearest whole number.
