Question 7) It was observed that 240 of the 400 voters randomly selected from a region supported the A candidate. According to this; a) Find and interpret the 95% confidence limits for the proportion of those who support candidate A in this region. b) When other conditions are fixed, at least how many units of sample should be taken so that the prediction error is less than 2%.
