Based on historical data at Portland State University, we believe that 44% of first year students do not visit their advisors regularly. For this year, you would like to obtain a new sample to estimate the proportion of first year students who do not visit their advisors regularly. You would like to be 99% confident that your estimate is within 4% of the true population proportion. How large of a sample size is required? Do not round mid-calculation.

You have been asked to estimate the proportion of households in Chicago that have two or more vehicles. a) How many households would you need to sample to be within 2 percent of the proportion of all households in Chicago that have two or more vehicles at a 90% level of confidence. b) You conduct a small preliminary sample, and you obtain a sample proportion of 19.5% that have two or more cars. Using this new information, what sample size should you gather in order to be within 2 percent of the proportion of all households in Chicago that have two or more vehicles at a 90% level of confidence.
