Answer:
The margin of error for this confidence interval is of 7.
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
The margin of error is the subtraction between these bounds, divided by 2.
In this question:
The bounds are 32 and 46.
(46 - 32)/2 = 14/2 = 7
The margin of error for this confidence interval is of 7.
