(3 pts) In a college student poll, it is of interest to estimate the proportion p of students in favor of changing from a quarter-system to a semester-system. How many students should be polled so that we can estimate population proportion to within 0.09 using a 99% confidence interval? A small study has been done, that found a sample proportion of 0.35
