Answer:

Hope this helps :D

Step-by-step explanation:

Answer to question .2

Girls-226

Boys-295

Boys with glasses- 210

Girls with glasses- 104

Difference Between boys and girls- 69

Difference between boys with glasses and no glasses-85

Difference between girls with glasses and no glasses-122

Answer 2

[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: $\frac{38+46+52+44+47+55}{6}$ = 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: $\frac{8+0+3+5+1+9}{6}$ = 4 $\frac{1}{3}$

->  4 $\frac{1}{3}$ = 4.33333 and when rounded to the nearest tenth is 4.3

Have a nice day!
