Answer:
14.625
Step-by-step explanation:
As per the situation the solution of mean and standard deviation change, based on all 12 samples is represented below:-
Mean of all 12 samples is shown below:-
So, the Mean = 23.5
and now,
The Standard deviation of all 12 samples is shown below:-
= 14.625
Therefore, we used the above equation to reach the answer.

Answer:
Box D = 27 ft³
Step-by-step explanation:
To find out which has the greatest volume, we need to calculate the volume of each box given in the option using the formula of the volume of a rectangular prism = w × h × l.
Where w = width; h = height; and l = length.
Thus, the volume for the boxes are as follows:
=>Box A:
V = w × h × l
V = 3 × 1 × 5
V = 15 ft³
=>Box B:
V = w × h × l
V = 2 × 3 × 4
V = 24 ft³
=>Box C:
V = w × h × l
V = 1 × 2 × 7
V = 14 ft³
=>Box D:
V = w × h × l
V = 3 × 3× 3
V = 27 ft³
The shipping box with the largest volume is box D with a volume of 27 ft³
