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* = 55 % . You would like to
be 99% confident that your esimate is within 2% of the true population proportion.
What is the critical value z* for the corresponding 99% confidence level?
z* -
(Report answer accurate to 2 decimal places.)
The sample should contain at least
individuals. (You should use the z* from your previous
answer with 2 decimals. You answer should be an integer.)
