Kalia Rodich

Will we receive our grade in addition to the bins? Thanks for all your logistical mindfulness professor!
Kalia Rodich
12:34
Thanks!
Rebecca Hu
17:53
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
