Answer:
Mean = 15
Standard deviation = 1.94
Step-by-step explanation:

We treat favoring of building a police substation as a success.
P(Success) = 75% = 0.75
Then the number of citizens follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 20
We have to find the mean and the standard deviation.
Thus, the mean of favoring the substation is 15 and the standard deviation of favoring substation is 1.94
