Question 3 • EHS Content Recovery - Probability and Statistics - Part D
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?
Answer
A
Yes, because 0.3525 is in the interval.
B
Yes, because the entire interval is greater than 0.25.
C
No, because there are values in the interval greater than 0.3525.
D
No, because the center of the interval is 0.3525, which is not statistically greater than 0.25.
