A family went out to eat. Below is the number of coen dogs tbat each of the four people ate. Find the mean absolute deviation (mad) of the data set.

1.25

Step-by-step explanation:

Give the data:

X : 1 1/2 ___ 0 4 2 1/2

Mean absolute deviation (MAD) :

Σ|x - xbar| ÷ n

xbar = Σx/ n

Σx = (1 1/2 + 0 + 4 + 2 1/2) = 8

xbar = 8/4 = 2

|x - xbar| :

|1 1/2 - 2|= 1/2

|0 - 2| = 2

|4 - 2| = 2

|2 1/2 - 2| = 1/2

Therefore,

MAD = (1/2 + 2 + 2 + 1/2) / n

MAD = 5/4

MAD = 1.25

we don't have enough info to solve this

a.)the line for function b is steeper
