Question 15 • Probability and Statistics with Applications Honors Sem-2-FL-1210300 (2024-2025)
A local dentist is concerned that less than half of her patients floss daily. A 95% confidence interval for the true proportion of her patients who floss daily is (0.325, 0.701). Is it reasonable to believe that less than half of her patients floss daily?
Answer
A
Yes, because 0.50 is in the interval.
B
Yes, because the majority of the interval is less than 0.50.
C
No, because there are values in the interval greater than 0.50.
D
No, because the interval has a lower bound of 0.325, which is not statistically lower than 0.50.
