Answer: The modal amount spent =$ 19
The median amount spent = $21
Step-by-step explanation:
Given: The amount spent on food and drink by 20 customers :
40 25 8 36 18 15 24 27 43 9 12 19 22 34 31 20 26 19 17 28
To find median, we need to first arrange all the number in order.
8 ,9 ,12 ,15 , 17 ,18 ,19 ,19, 20 , 22 , 24 , 25, 26 , 27 , 28,31 ,34 ,36 ,40,43
Since , the number of value is even.
then Median = Mean of two middle most numbers
[tex]\Rightarrow\text{Median}=\dfrac{20+22}{2}=21[/tex]
Mode = Most repeated number = 19
Hence, The modal amount spent =$ 19
The median amount spent = $21
