Suppose that 275 students are randomly selected from a local college campus to investigate the use of cell phones in classrooms. When asked if they are allowed to use cell phones in at least one of their classes, 40% of students responded yes. Using these results, with 95% confidence, the margin of error is 0.058 . How would the margin of error change if the sample size decreased from 275 to 125 students? Assume that the proportion of students who say yes does not change significantly. As the sample size decreases, the margin of error remains unchanged. Cannot be determined based on the information provided. As the sample size decreases, the margin of error increases. As the sample size decreases, the margin of error decreases.
