Calculator

errant sandal
#

Are you using the cumulative distribution function?

rain scroll
#

Yea

errant sandal
#

Then subtracting the value from 1?

#

1 - p(x</= 8)

rain scroll
#

Yea I think you have to do that

#

Cause we are looking at upper end of critical region?

#

But I don't think that is right

errant sandal
#

Well I’m not rlly that good at hypothesis tests

#

Explain why u don’t think it’s right

exotic hill
#

1-0.99001821
= 0.0098

#

hm

rain scroll
#

Wait Bicen maths this jokeman got 0.01 it's last question of the last video on hypothesis testing

errant sandal
#

Link the video

rain scroll
exotic hill
#

it's definitely 0.0098

#

100%

#

I just did it in my cg50

rain scroll
#

Yea are you 100% same but idk

exotic hill
#

yeah

rain scroll
#

Like 100%

exotic hill
#

I didn't do 1- cus u don't have to

#

but still

rain scroll
#

Yea he did it wrong

exotic hill
#

oh wait

#

no he didn't

errant sandal
#

I got what Bicen got

rain scroll
#

Oh my I am confused

errant sandal
#

But like I said I’m generally bad at these questions so idk

rain scroll
#

Is it cause he looked at the upper region

#

Wait I am right

#

He just rounded it

exotic hill
#

😭

rain scroll
#

0.0098 is 0.01

exotic hill
#

yeah

rain scroll
#

Rounded

exotic hill
#

well

rain scroll
#

Oh my

exotic hill
#

rain scroll
#

No

#

Yea it is

brittle jackal
#

isnt the upper tail x>=9

rain scroll
#

It should be 9

#

Yea

brittle jackal
#

OKAY cool thought i was buggin

rain scroll
#

He missed it

#

He forgot

errant sandal
#

Why is that wrong?

brittle jackal
#

on the bottom left when he was looking at the upper tail he found out that it was when x>=9

#

so the critical region should be x=0 or x>=9 but he wrote 8

#

thats all

#

kinda did it the long way but yeah
