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
