A researcher wishes to estimate, with 90% confidence, the proportion of adults who have-speed Internet access. Her estimate must be accurate within 4% of the proportion. Find the maximum sample size needed, using a prior study that 32% of the respresentation said represents said they have high-speed Internet access. No preliminiary estimates is available. Find the minimum sample size needed. What is the minimum sample size needed using a prior study that found that 32% of the representation said they have high-speed Internet access? n = What is the minimum sample size needed assuming that no preliminary estimate is available? n =
