Answer:
The mean absolute deviation of the data set is 2.4
Step-by-step explanation:
To determine the mean absolute deviation (MAD) of the data, we start by finding the mean of the data set.
The mean is obtained by finding the sum of the data values, and then dividing the sum by the number of data values.
Find the absolute value of the difference between each data value and the mean: |data value – mean|.
Find the sum of the absolute values of the differences.
Divide the sum of the absolute values of the differences by the number of data values.

Answer:
The discount is the same.
Step-by-step explanation:
We need to find the ratios of both discounts.
41/50 = 61.5/75
If the question is True, this means that the ratios should be the same. So we have to cross multiply to find the answer.
75*41 = 50*61.5 = 3075
These two multiplication problems both equal 3075. Since the ratios are equal, the discounts are also equal.
