hat percentage of your campus student body is female? Let p be the proportion of women students on your campus. (a) If no preliminary study is made to estimate p, how large a sample is needed to be 80% sure that a point estimate p̂ will be within a distance of 0.042 from p? (b) A report indicates that approximately 55% of college students are females. Answer part (a) using this estimate for p.

Biologists studying horseshoe crabs want to estimate the percent of crabs in a certain area that are longer than 35 centimeters. The biologists will select a random sample of crabs to measure. Which of the following is the most appropriate method to use for such an estimate?

Using the following scenario, calculate the value of the point estimate. What proportion of students are willing to report cheating by other students? A student project put this question to an SRS of 229 undergraduates at a large university: "You witness two students cheating on a quiz. Do you go to the professor?" Only 25 answered "yes". Round your answer to two decimal places.
