The data points that fall within the mean absolute deviation are 2.9 and 3.1.
<h3>What is the mean absolute deviation?</h3>
The mean absolute deviation is the mean average distance between every data point and the mean of the data set.
From the information given:
- Mean of the data set = 5.3
- Mean absolute deviation = 2
The mean absolute deviation is:
= (|5.3 - 2|)/1
= 3.3
Thus, the data points that fall within the mean absolute deviation are 2.9 and 3.1.

PART B: E,B and C, A
Step-by-step explanation:
Part B is all I can help you with. (I'm Sorry)
Step-by-step explanation:
° put the value of x at the place of x to get y , put value of y to get x.
° x = -4
y = -2x + 3
y = -2(-4) + 3
y = 8 + 3 = 11
° x = -1
y = -2(-1)+3
y = 2 + 3
y = 5
• y = 3
y = -2x + 3
3 = -2x + 3
0 = -2x
x = 0
• y = -3
-3 = -2x + 3
-6 = -2x
x = 3
