Answer:
Mean = 15
Standard deviation = 1.94
Step-by-step explanation:
We are given the following information:
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
Answer:
Yes because 1.31 and 1.2. 3 is more than 2
Step-by-step explanation:
It would be 13 becsue 12.5 time 2 = 25 so round that it = 13
15 miles 2.5 x 6 because 1/4th of an hour is 15 minutes 15 x6 = an hour and a half
