Answer: Option C. [0.95, 1.59].
Step-by-step explanation:
We know that the mean is:
M = 1.27
and the margin of error is:
e = 0.32
This means that the actual value can be at a maximum distance of 0.32 from the mean.
then the interval will be:
[M - e, M + e].= [1.27 - 0.32, 1.27 + 0.32].= [0.95, 1.59].
The correct option is C.
