Question

I just need a little help so i can bring my f up to a d so i can pass math :)

Answer 1

Answer:

Step-by-step explanation:

Mode: Mode is the value that appears most often in the data set

 115 , 32, 48 , 11 , 112 , 67 , 91 , 11 ,160 , 11 , 91 , 128 , 147

Here 11 comes 3 times

So, mode = 11

$\sf \boxed{\text{Mean = \dfrac{sum \ of \ all \ the \ data}{number \ of \ data \ sets} }}$

         $\sf = \dfrac{245 + 65 + 123 + 100 + 22 +43 + 36+ 177 + 21 }{9}\\\\ =\dfrac{832}{9}\\\\= 92.4$

Mean = 92.4

Range :

3) Range = maximum value - minimum value

            = 297 -  19

            = 278

4) Range = 129 - 6

                = 123

Median: Arrange the data  set in ascending order and find the middle term

5) 3 , 3 ,3  , 21 , 87 , 100 , 124,  174 , 191

n = 9

As the number of terms is odd number,

  $Median = (\dfrac{n+1}{2})^{th} \ term$

                 $\sf = (\dfrac{9+1}{2})^{th} \ term\\\\= (\dfrac{10}{2})^{th} \ term\\= 5^{th} \ term$

                 = 87
