We are planning on introducing a new internet device that should drastically reduce the amount of viruses on personal computers. we think the price should be $39.99, but are not sure on the percentage of people that would buy it. we do some research and find the following information; studies from the 1980’s indicate that percentage should be between 30% and 40% similar products were launched recently at a price of $4,000 and nobody bought it. a nationwide poll on this type of product and price was run earlier this year, with percentages running from 55% to 65%. we are going to conduct an additional focus group before we launch the product. what should the sample size be if we want a 90% ci to be within 5% of the actual value?
