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=45%. You would like to be 98% confident that your estimate is within 1% of the true population proportion. How large of a sample size is required? no any intermediate rounding a) Which of the following is most appropriate to use as an approximate for the critical value in this application?

• 1.5
• 1.96
• 1.65
• 2.33
• 2.58
• b) Using the critical value from the estimate above, the sample should contain at least [ ] individuals.
