Sagot :
Using confidence interval concepts, it is found that the margin of error is of 7.
- A confidence interval has the format (a,b).
- The margin of error is half the difference between the two bounds, that is:
[tex]M = \frac{b - a}{2}[/tex]
In this problem, the interval is (32, 46), hence [tex]b = 46, a = 32[/tex], and the margin of error is:
[tex]M = \frac{46 - 32}{2} = 7[/tex]
The margin of error is of 7.
