When will grade reports be released?

Kalia Rodich

11:06

What are grade reports?

Will we receive our grade in addition to the bins? Thanks for all your logistical mindfulness professor!

Kalia Rodich

12:34

Thanks!

Rebecca Hu

Reject null that b1 = 0

isaacecheto

17:57

Beta1. Is not 0

isaacecheto

18:00

^

Rebecca Hu

18:16

Accept null that b1 = 0

Rebecca Hu

18:19

b0*

Ashley Minooka

19:32

if you use the CI?

Ashley Minooka

19:34

maybe?

Rebecca Hu

19:48

Or use the given p-val

Stephen N

20:22

use coefficients?

isaacecheto

20:30

And se

alvin

20:30

coefficient/SE

isaacecheto

Matthew Simon

21:42

Is the null always beta zero or beta 1 is 0?

Matthew Simon

22:05

Thanks

alvin

23:07

use the t distribution

Ashley Minooka

23:19

from using the SE?

Stephen N

23:29

use 95% CI

Joshua Kim

26:08

Sorry which one is used when n is large again?

Joshua Kim

26:42

gotcha

Celine Wherritt

26:59

Does the 2nd one say (t, df = m^2)?

isaacecheto

27:19

n-2

Celine Wherritt

27:24

Got it thanks

Rebecca Hu

27:28

Coefficient +- 2(se)

Jack Troyan

27:34

so 230?

Rebecca Hu

30:38

Yes by using r?

isaacecheto

31:03

You can use SE(beta1hat) to fix sd (x)

isaacecheto

31:07

find*

Jack Troyan

31:41

set mu y = mu x*beta1 + beta 0

Jessie

34:33

do these formulas only apply because n is large

Joshua Kim

34:35

I have a final logistics question: are we going to get a similar reference sheet like we had for the midterm?

Ashley Minooka

34:58

can't see the diagram?

Joshua Kim

35:00

Can anyone see the screen?

Dorkhan Chang

35:09

no

Anna Shim

35:09

nope

chelsi

35:10

We can’t see your screen professor

Ashley Minooka

35:11

I don't think the screen is being shared

chelsi

35:11

nope

Sophie

35:11

Professor I think you stopped screen sharing

Tanvee Joshi

35:12

no

Stephen N

35:12

no

Jolana Chan

35:13

can’t see

Ashley Minooka

35:37

yay

Joshua Kim

35:43

I can see it now

Ashley Minooka

36:19

no, because the data isn't linear or a football shaped cloud?

Ashley Minooka

36:42

uh, an exponential function would fit better

Ashley Minooka

37:16

the error is no longer normally distributed along the line right now

alvin

42:17

constant and weight coefficient could be 0

isaacecheto

42:44

Accept null of beta0 and beta2 = 0, reject null of beta1 = 0

Rebecca Hu

42:46

Accept null for b0 and b2 reject b1

Dorkhan Chang

45:52

so if pvalue for B2 is low, then r^2 will most likely be better?

Rebecca Hu

47:08

b0 + b1*50 + b2*150 ?

Ashley Minooka

47:28

do we want to include coeffs deemed insignificant?

isaacecheto

50:04

Top is stats

isaacecheto

50:09

Bottom is prob

Jingyu Han

50:10

First one is statistics second one is probability

Ashley Minooka

57:28

slowly

Dorkhan Chang

01:00:44

why is d less than or equal to 40?

Jesse Thiara

01:01:06

Hi, Just wondering if we could get some insight on how to do homework question 3a and 3c "without any calculation" are these supposed to be effectively educated guesses or is there somewhere I can look for a method to find a range
