Finding the sample size: Polls are to be conducted in two cities to determine the difference in the proportions of residents who believe that the economy will improve over the next year. A 98% confidence interval will be constructed for the difference between the proportions. If the sample sizes are to be equal in the two cities, how large should each sample be so that the margin of error will be no more than 0.08? Round up your answer to the nearest whole number. Each sample should contain a minimum of residents. DEC MacBook Ar DD F9 F10 FB F7 F5 F2 F3 F4
