Give your answer in whole people. 0 Question 5 v B 0/2 pts '0 3 8 99 G) Details You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the population proportion. You would like to be 90% condent that you esimate is within 1% of the true population proportion. How large of a sample size is required? Do not round mid-calculation. However, use a critical value accurate to three decimal places. Question 3 0/2 pts 9 3 99 0 Details Assume that a sample is used to estimate a population proportion p. Find the margin of error M.E. that corresponds to a sample of size 382 with 18.1% successes at a confidence level of 99%. M.E. = % Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places. Round final answer to one decimal placeQuestion 2 > 0/2 pts 5 3 99 8 Details We wish to estimate what percent of adult residents in a certain county are parents.
