Yeah Oh Shar everybody out of the water So you're

not reading this while treading in the salty seas clients
- 00:17
They we are Everything's fine All right When we think
- 00:19
of sharks we might not think of them as scavengers
- 00:22
But in addition to hunting a great white shark also

forages for meat One study here looked at how scavenging
- 00:29
affect the behavior of white sharks and their relation to
- 00:31
their physical surroundings For the study the team monitored white
- 00:35
sharks feeding off a dead whale carcass in False Bay
- 00:37
South Africa Study found that large sharks might be drawn
- 00:42
into the bay away from their migration routes by high
- 00:45
winds as these winds help the water transport the scent
- 00:48
of that you know dead whale And no this is
- 00:51
not an allegory for America's a congressional system So table
- 00:56
one below shows the recorder data from each scavenging event
- 00:59
in this study All right so we're gonna kind of
- 01:01
skin this thing and try to figure out what it's
- 01:03
all about Got whale species in size and wind direction
- 01:07
and speed and temp on probation Boy they really follow
- 01:10
things Figure one illustrates the relationship of wind speed Teo
- 01:15
Maximum Shark's eyes straight line and figure one is a
- 01:19
linear regression fit to the data points to illustrate a
- 01:21
direct relationship between wind speed and maximum shark sides Okay
- 01:27
so let's just get right down here The questions according
- 01:29
to the data that most sharks were recorded on the
- 01:33
wind So what We're going to look data here gets
- 01:37
the regression people where we look well The maximum number
- 01:41
of sharks observed in a scavenging event is forty That's
- 01:44
forty sharks You know we've been practicing our shark flipping
- 01:47
but we're pretty sure we don't stand a chance against
- 01:51
that many sharks Good thing these sharks have a much
- 01:53
taste your meal in front of them It's fatter than
- 01:55
we are The whale is still Each row of table
- 01:58
one represents data collected from one feeding event When a
- 02:02
bunch of sharks find a whale carcass and basically have
- 02:04
a dinner party for the feast with the most inter
- 02:08
guests can be found by looking at the column labeled
- 02:10
Max Number Sharks right there and just scanning for the
- 02:14
greatest number Not once we see that forty is greater
- 02:18
than all the rest Well we can check out its
- 02:20
date right there in the second column on the same
- 02:23
road So in the first row we see that forty
- 02:25
sharks were found circling a whale carcass on July fifth
- 02:28
two thousand A belated if Independence Day celebration Maybe Well
- 02:34
that's it The answer is deep What do you think
