00:00

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

00:14

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

00:25

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
