Answer:
The mean doesn't represent the center of data accurately because there is one outlier in the data that is 150
So, the correct answer is FALSE.
The mode represent the center of data most accurately because the most common data is at the center of the data spread
So, the correct answer is TRUE
The median represent the center of data accurately because it is close to the amount that was spent most of the time.
So the correct answer is TRUE
The range doesn't represent the center of data because there is one outlier at the end so the range will shift to right of the center.
So, the correct answer is FALSE.
PART B :
The data in the ascending order is : 25,25,40,40,44,44,48,48,50,54,54,54,56,60,150
Median of the first half of the data = 40
Median of the second half of the data = 54
SO, IQR = 54 - 40
= 14 ≠ 35
Hence, the correct IQR for the data is 14
