Question

Please help :) I don’t understand this

Answer 1

Answer:

Step-by-step explanation:

Part A

Neighborhood A :

2, 2, 2, 4, 4, 5, 5, 5, 5

mean = $\frac{2+2+2+4+4+5+5+5+5}{9}$ = $\frac{34}{9}$ ≈ 3.8  

median = 4

mode = 5

range = 3

$Q_{3}$ - $Q_{1}$ = 5 - 2 = 3

===================

Part B.

Neighborhood B :

1, 1, 2, 2, 3, 4, 5, 5, 12

mean = ( 1 + 1 + 2 + 2 + 3 + 4 + 5 + 5 + 12 ) ÷ 9 = $\frac{35}{9}$ ≈ 3.9

median = 3

mode = 1, 2, 5

range = 11

$Q_{3}$ - $Q_{1}$ = 5 - 1.5 = 3.5

Outlier = 12
