Based on the limited amount of available student parking spaces on the GSU campus, students are being encouraged to ride their bikes (when appropriate). The administration conducted a survey to determine the proportion of students who ride a bike to campus. Of the 120 students surveyed 5 ride a bike to campus. Which of the following is a reason the administration should not calculate a confidence interval to estimate the proportion of all students who ride a bike to campus? Check all that apply. The sample needs to be random but we don’t know if it is. The actual count of bike riders is too small. The actual count of those who do not ride a bike to campus is too small. n * ^ p is not greater than 10 . n *( 1 − ^ p )is not greater than 10 .
