Given:
Consider the below figure attached with this question.
The given data set is:
66, 65, 66, 70, 66, 68, 63, 60, 66, 68, 63, 65
To find:
The correct box plot for the given data set.
Solution:
We have,
66, 65, 66, 70, 66, 68, 63, 60, 66, 68, 63, 65
Arrange the data set in ascending order.
60, 63, 63, 65, 65, 66, 66, 66, 66, 68, 68, 70
Divide the data set in 4 equal parts by using the parenthesis.
(60, 63, 63), (65, 65, 66), (66, 66, 66), (68, 68, 70)
Minimum value = 60
First quartile:
Median:
Third quartile:
Maximum value = 70
It means the end points of the box plot are 60 and 70. The box lies between 64 and 67. Line inside the box at 66.
The box plot in option A is the only box plot that satisfy the above conditions.
Therefore, the correct option is A.
Answer:
60 players should be produced to minimize the marginal cost
Step-by-step explanation:
Following the problem instructions, the marginal cost function is:
Then, to find the x players at would has its minimum value, we have to find the first derivative as follows:
And the minimum value is determined when:
Then, we solve for x, and these would be the players produced to minimize the marginal cost:
That means at least 60 thousand players must be produced in order to minimize the marginal cost.
