Calculate the measures of spread for Mrs. Hampton’s class data. Justify your response by describing the process used to find each measure. (10 points) Can you please help.
I'm kinda dum.b and I don't really understand whats going on. Please don't answer just for points.

Step-by-step explanation: Dot plot for movies seen by a students in a month

To Find : measures of spread

Solution:

Movies frequency cumulative frequency

0 1 1

1 0 1

2 0 1

3 0 1

4 3 4

5 8 12

6 3 15

7 1 16

8 5 21

9 2 23

10 3 26

Range = 10 - 0 = 10

Q2 = (6 + 6)/2 = 6 (13th + 14t)/2

Q1 = 5 7th

Q3 = 8 20th

IQR = Q3 - Q1

= 8 - 5

= 3

B

Step-by-step explanation:

Since all the expressions are on a straight angle (equalling 180) combine the expressions to form on big expression that is equal to 180 and solve.

6x - 10 + 4x + 6 + 7x + 14 = 180

17x + 10 = 180

      - 10    -10

17x = 170

÷17    ÷17

x = 10

Hope this helps
