Answer:
[tex]Mean = 38.9[/tex] [tex]Median = 40[/tex]
Step-by-step explanation:
When you find mean, you must add all the numbers together then divide by the amount of numbers.
[tex]10+31+36+36+38+42+47+48+49 + 52[/tex]
[tex]==> 389[/tex]
There are 10 numbers.
[tex]389 / 10[/tex]
[tex]==> 38.9[/tex]
To find median, you have to either find the middle number or find the two numbers that makes it equal. Since this range set is even, we use the second option.
[tex](x + y ) / 2[/tex]
[tex]38 + 42[/tex]
[tex]==> 80[/tex]
Divide by 2
[tex]80 / 2[/tex]
[tex]==> 40[/tex]
