A population has standard deviation ở =17.3. Part 1 of 2 (a) How large a sample must be drawn so that a 99.5% confidence interval for u will have a margin of error equal to 3.2? Round the critical value to no less than three decimal places. Round the sample size up to the nearest Integer. A sample size of is needed to be drawn in order to obtain a 99.5% confidence interval with a margin of error equal to 3.2. Part 2 of 2 (b) If the required confidence level were 99.9%, would the necessary sample size be larger or smaller? (Choose one) ▼ because the confidence level is (Choose one) v Larger Smaller
