You want to estimate the proportion of all college students who traveled during spring break.You survey a random sample of 200 college students and find that 116 of these students reportedtraveling during spring break. If you want to construct a 95% confidence interval, what will themargin of error be? Choose the answer that is closest to what you calculate, and try not to do alot of rounding until you reach the very end of your calculations.Greater than or equal to 0.10O Less than or equal to 0.010.070.050.03

Given that Sample size n =200 Favorable cases x =116 Sample proportion p^=x/n =116/200 =0.58

Mark each statement TRUE or FALSE. For these problems, assume that to estimate average time spent waiting at a restaurant, you sample 10 people and you get a 95% confidence interval of (5, 7) in minutes. If you increase sample size, the width of your confidence interval increases. If you increase confidence level, the width of your confidence interval increases.
