Answer:
The correct answer is A.
A) The IQR of Karla's data in 13.
Step-by-step explanation:
The interquartile range can be defined as the difference of upper quartile and lower quartile range. If we want to find the IQR from the box plot, we can simply see the length of the box from the box plot, as it represent the IQR.
We can clearly see that:
IQR of Steve's data is 45 - 31 = 14, hence the second statement is incorrect
IQR of Karla's data is 52 - 39 = 13, hence the first statement is CORRECT
The difference of medians is 43 - 36 = 7
Hence the difference of medians is not the half or twice of IQR ranges of both data sets
first you put 18/y=2
you multiply by 18 to get y=36
your answer is 36, y=36
