Thank you We sneak in and here's your shmoop du

00:05

jour brought to you by snow For once it didn't

00:08

flake on us Art alexander measured the amount of snow

00:14

that fell on his driveway each day last week His

00:17

results are shown in the following bar graph If he

00:19

didn't count the measurement for one of these days which

00:22

day would change the average amount of snow that fell

00:24

over the entire week The most select the appropriate part

00:28

of the graph Okay so apparently alexander doesn't want cold

00:37

much firstly and we'd like to just blow the stuff

00:39

off the driveway and get the heck back inside Okay

00:43

we got a bar graph here showing how much snow

00:45

fell each day of the week The question is asking

00:47

which day if omitted would change the average the most

00:51

In other words which days snowfall was the furthest away

00:55

from the average which is the way that you have

00:58

got it All right Well right away we can eliminate

01:01

tuesday thursday and friday if one day is going to

01:03

skew our results it'd have to be either the day

01:06

with the most snowfall or the day with the least

01:09

snowfall well from here and we just kind of have

01:11

to do the math so let's get the average snowfall

01:14

first but we had six plus four plus three and

01:17

a half plus three plus two and a half which

01:20

equals nineteen then divide by five to get nineteen fists

01:23

or about three point eight All right well wednesday the

01:26

day with the least snowfall is a two point five

01:28

while monday is at six so wednesday was one point

01:32

three less than the average seems a little number line

01:35

You know that But monday was a whopping two point

01:38

two more than average meaning it would change our results

01:42

the most if we excluded it though for alexander having

01:45

a case of the mondays seems to take on a 00:01:47.688 --> [endTime] totally different meaning
