According to a past study, it was believed that 1.4% of the students in the School district did not have access to a resources. Suppose you are planning to do a follow-up study to understand the current proportion of children in the School district that do not have access to resources. You suspect that the proportion is probably still close to 1.4%. How large should your sample be if you want the Margin of Error to be within 0.3% with a confidence level of 98%? (Be sure to show your calculations involving the formulas.) Keep in mind that the z* value for a confidence level of 98% is 2.326.
