Using the Central Limit Theorem, the correct option is:
(c) Average number of miles put on a rental car per day across 25 customers.
--------------------------
The Central Limit Theorem states that, for a normally distributed variable X, with mean
and standard deviation
, the sample means of size m are approximated to a normal distribution with mean
and standard deviation
.
- The interpretation related to this problem is that the larger the sample size, the smaller the standard deviation.
- Thus, among the options, the largest sample is 25, thus, option c will have the smallest standard deviation.

1 hour = 60 minutes.
Convert the minutes to decimals by diving by 60
30/60 = 0.5
2 hours and 30 minutes = 2.5 hours
45/60 = 0.75
5 hours 45 minutes = 5.75 hours
15/50 = 0.25
3 hours 15 minutes = 3.25 hours
Ow add all the hours:
2.5 + 5 + 5.75 + 3.25 = 16.5 hours
Answer: B. 16.50
As the cube has 6 faces the area of one face will be 864 / 6 = 144 in^2
so each edge = 12 in
Volume of cube = 12^3 = 1728 in^3
