Estimating Sample Size: You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately p* = 46 % . You would like to be 95% confident that your esimate is within 0.5% of the true population proportion. How large of a sample size is required? (please do not do any intermediate rounding) a) Which of the following is most appropriate to use as an approximate for the critical value in this application? O1.5 O 2.58 1.65 O 2.33 O1.96 b) Using the critical value from the estimate above, the sample should contain at least individuals.
