[Problem 2]
-> Girls = 226
-> Boys = 295
-> Girls with glasses = 104
-> Boys with glasses = 210
-> Difference of total boys and girls = 69
-> Difference of boys with glasses vs without glasses = 85
-> Difference of girls with glasses vs without glasses = 122
-> It is hard to create a table over Brainly
[Problem 4] Answer is 4.3
-> To find the mean absolute deviation, we will find the mean of the data and then see how far away each point is, and then find the mean of those values
-> Finding mean: [tex]\frac{38+46+52+44+47+55}{6}[/tex] = 47
-> All the values (all of the values will be absolute values, why the word absolute is there, so ignore all negative signs!)
38 - 47 = 9
46 - 47 = 1
52 - 47 = 5
44 - 47 = 3
47 - 47 = 0
55 - 47 = 8
-> Then, we will find the mean of these values: [tex]\frac{8+0+3+5+1+9}{6}[/tex] = 4 [tex]\frac{1}{3}[/tex]
-> 4 [tex]\frac{1}{3}[/tex] = 4.33333 and when rounded to the nearest tenth is 4.3
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
