b) A researcher wish to estimate, 95% confidence, the proportion of people who did not have a land line phone. A previous study that 40% of those interviewed did not have a land line phone. The researcher wishes to be accurate within 4% of the true proportion. Find the minimum sample size that necessary.

An environmental agency worries that many cars may be violating clean air emissions standards. The agency hopes to check a sample of vehicles in order to estimate the percentage with a margin of error of 5% and 95% confidence. To gauge the size of the problem, the agency first picks 40 cars and finds 8 with faulty emissions systems. How many should be sampled for a full investigation?
If the population proportion is 0.7 . A researcher wants the margin of error to be 0.20 and the level of confidence is 95% . What is the require sample size?
