A 95% confidence interval for the true proportion of teenagers who have been to a professional sporting event is (0.289, 0.416). Is it reasonable to believe that more than 25% of teenagers have been to a professional sporting event?
Yes, because 0.3525 is in the interval.
Yes, because the entire interval is greater than 0.25.
No, because there are values in the interval greater than 0.3525.
No, because the center of the interval is 0.3525, which is not statistically greater than 0.25.
