Answer:
The correct option is D
D) She may not be correct because means cannot be determined from the box plots
Step-by-step explanation:
The question is incomplete because the box plots are not attached in the question. I've attached the box plots of this question at the bottom.
The box plot, also know as box and whisker plot, displays only five type of values, which are:
- Minimum value
- First Quartile
- Median
- Third Quartile
- Maximum value
Mean cannot be determined by just lookin at the box plots. To find the mean, we need to know the values of data and total number of values.
As mean cannot be determined from the box plot, correct option is D

Perimeter of a square = 4s
Required perimeter =
It is related to econometrics, however using simple algebraic logic we can solve this problem. General formula with residual is

, where r is a residual. Plugging the pair into the formula, we obtain that

and r=0.5
