In order to estimate the proportion of individuals who read at least one book per month, a random sample of individuals was selected and they were asked whether or not they read at least one book per month. Their responses are shown below. Responses Yes, I read at least one book per month No, I do not read at least one book per month Frequency 490 210 (a) Develop a 95% confidence interval for the proportion of people in the population who read at least one book per month? Round your answer to three decimal places. Show all steps. (b) Based on the 95% confidence interval in (a), is it reasonable that the population propoprtion of people who read at least one book per month is 0.75? Justify your answer. (c) Interpret the confidence interval in (a).
