Option C is right
Step-by-step explanation:
Given that the random variable, X, the ages of voters as per poll worker analysis is having mean as 65 and std deviation as 5
X is normal (65,5)
To convert to Z score from x we use
Z = 
Or we can write in terms of x as
X = 65+5z
When z = 1.14
we can convert into z as follows
X=65+5(1.14) = 65+5.7=70.70
Round off to 71
