a. Let p be the proportion of households in Abbotsford having an exotic pet. Suppose you want to construct a 90% confidence interval for p with a margin of error of 0.05, how large should the sample size be? (Assume that you do not have any knowledge or prior sample about the population proportion p.) (b) Suppose that in a random sample of 350 households in Abbotsford, it is found that 41 of them have an exotic pet. Construct an adjusted 95% confidence interval for the proportion of households in Abbotsford having an exotic pet. What is the margin of error in this case?
