10. You want to estimate the proportion of all college students who traveled during spring break.   You survey a random sample of 1,800 college students and find that 1,044 of these students reported traveling during spring break.  If you want to construct a 95% confidence interval, what will the margin of error be?  Choose the answer that is closest to what you calculate, and try not to do a lot of rounding until you reach the very end of your calculations. 1. 0.04 2. Less than or equal to 0.01 3. Greater than or equal to 0.10 4. 0.07 5. 0.02
