ANSWER
SET A:
Mean = 11.08
Mean Absolute Deviation (MAD) = 1.43
SET B:
Mean = 10.08
Mean Absolute Deviation (MAD) = 1.60
EXPLANATION
Given:
From the question, 20 chips (samples) were randomly selected from the 100 colored chips by each seventh grade student (assuming you are one of).
These 20 random selected chips contained both male and female but the percentage of each was yet to be given.
Now, the percentage of only the male students was given and this was used to generate the data sets.
Recall, both sets of numbers must include exactly twelve data points.
SET A
Given Thirty Random Samples, select the first 12 samples for SET A.
[tex]\begin{gathered} \text{1. }\frac{55}{100}\times20\text{ = 11} \\ 2.\text{ }\frac{65}{100}\times20\text{ = 13} \\ \text{.} \\ \text{.} \\ \text{.} \\ 12.\frac{60}{100}\times20\text{ = 12} \end{gathered}[/tex]SET B
Given Thirty Random Samples, select the last 12 samples for SET B.
[tex]\begin{gathered} 1.\text{ }\frac{45}{100}\times20\text{ = 9} \\ \text{2. }\frac{50}{100}\times\text{20 = 10} \\ 3.\text{ }\frac{55}{100}\times20\text{ = 11} \\ \text{.} \\ \text{.} \\ \text{.} \\ 12.\text{ }\frac{50}{100}\times20\text{ = 10} \end{gathered}[/tex]Data for SET B
