APSTAT-LLUKXB

In an effort to determine what percentage of teenagers text and drive at Griswold High School, a student randomly selected $50$ teenage drivers from Griswold and constructed a $95\%$ confidence interval. Suppose that the student decides to construct the $95\%$ confidence interval again, but this time she randomly selects $100$ students.

What would happen to the margin of error?
