At a 95% confidence interval for p, the proportion of all US adults who exercise regularly is 0.562 to 0.684. Is it reasonable to believe more than two-thirds of US adults exercise regularly?
Answer
A
Yes, because 0.667 is in the interval.
B
Yes, because there are values greater than 0.667 in the interval.
C
No, because there are values less than 0.667 in the interval.
D
No, because the center of the interval is 0.623, which is less than 0.667.
