Work Step by Step
1. Find the sample mean (average) of the data.
First step: Add the rows together, one by one.
30 30 30 60 40 30 40 = 260
30 40 15 30 30 90 30 = 265
30 60 60 30 60 30 100 = 370
30 30 60 30 60 60 30 = 300
30 30 30 40 105 60 40 = 335
15 30 30 30 15 30 60 = 210
60 30 40 40 40 60 40 = 310
30 30 30 60 30 30 60 = 270
30 30 30 60 40 40 40 = 270
30 100 30 30 30 30 30 = 280
40 15 30 30 60 30 30 = 235
40 30 40 40 60 30 30 = 270
30 30 40 40 30 30 30 = 230
30 30 30 60 30 30 30 = 240
30 30 = 60
----------------------------------
= 3905
Second Step: Take the fines (in Canadian dollars), 3905, divided by 100 parking infractions.
$3905/100 = 39.05$
