Jingyu Han
01:47
yes
ireneyoon
01:48
YES
YeJin Ahn
01:54
yes
Kaci Gu
04:08
a straight line?
Zachary Zhu
04:29
Horizontal line <=0, >=2, slope of 1 from 0-2
isaacecheto
04:45
(0, ½) to (2, 3/2)
isaacecheto
04:54
Ah ok
isaacecheto
04:59
1/2
ashley minooka
05:02
1/2
Zachary Zhu
05:02
Slope of 1/2—my b
YeJin Ahn
07:22
8/3 not 1/3?
YeJin Ahn
07:26
4/3*
Kaci Gu
07:45
Could you explain why we’re using 1/2
chelsie park
07:45
How do you know the expectation of v
Kaci Gu
08:18
yes
Kaci Gu
08:20
thank you
Sophie Liu
08:47
value at the center of the distribution
Andrew
08:49
2*1/2?
chelsie park
09:16
Got it
chelsie park
09:17
thank you
Nicki Minaj
09:18
Professor I have a question…
isaacecheto
15:08
b-a
lauraherron
15:55
b-a
mayareuven
15:56
B-a
Rebecca Hu
15:56
B-a
chelsie park
15:56
B-a
isaacecheto
16:14
u(b-a) + a?
lauraherron
16:18
+a
ashley minooka
19:03
Is E(U) specifically the expected value of the standard uniform?
isaacecheto
23:37
1/7
Rebecca Hu
23:41
7/5?
ashley minooka
23:46
1/5
isaacecheto
23:50
ah
YeJin Ahn
23:53
1/5
isaacecheto
23:55
^
ashley minooka
24:59
why is (P<= x) to the 7th power?
Kaci Gu
25:22
they’re iid
ashley minooka
25:35
oh
ashley minooka
25:45
so we're multiplying 7 different but identical probabilities?
celinewherritt
25:51
yes
Kaci Gu
25:52
i believe so
ashley minooka
25:54
ty!!
Kaci Gu
26:04
does anyone know why the height is 1?
YeJin Ahn
26:24
why is it x-3:07/5?
Dorkhan Chang
26:25
what is F(x)
isaacecheto
26:34
I think so
Carina Massana
26:59
Is the CDF not 1 after 3:12?
Zachary Zhu
27:01
Why isn’t F(X) = 1 when x >= 3:12?
YeJin Ahn
28:20
why are you dividing it by 5..?
Joshua Kim
28:29
Can you repeat how you got x-3:07/5?
celinewherritt
29:31
So for a uniform distribution the height is always 1?
Kaci Gu
29:46
^same question
Joshua Kim
31:06
No I just missed the CDF part
isaacecheto
31:27
Is x-a/(b-a) a reliable formula for cdf of uniform
celinewherritt
31:43
Okay thank you
Kaci Gu
31:45
Got it thank you!
alvin
31:54
how does the graph of f(x) relate to the transformation shifts for uniform distributions
isaacecheto
31:58
Ok cool
celinewherritt
34:54
0.45
YeJin Ahn
34:54
0.45
Dorkhan Chang
46:15
so mean is 1/lambda?
celinewherritt
46:27
On a quiz/midterm, would we be expected to do integration by parts
Forrest Kim
47:39
yes
ireneyoon
47:39
yes
Joshua Kim
47:40
yes
ashley minooka
47:47
maybe (yes)
Joshua Kim
47:51
YAY!
chelsie park
48:18
thank u professor :)))
isaacecheto
49:24
P(x > 48)?
Jooee Karwande
49:25
x>48
Jooee Karwande
49:26
?
ashley minooka
50:29
thank u!
mayareuven
50:31
thanks!
Jingyu Han
50:32
Thank you!
Ronan Figueroa
50:33
thank you
Sophie Liu
50:34
thanks!
Tanvee Joshi
50:34
thank you!
Jessica Ornowski
50:35
how did you get 48?
Ryan Dai
50:42
thanks!
isaacecheto
50:44
Hav a nice weekend prof
Joshua Kim
50:48
So how did you get 1/24 again?
Jooee Karwande
50:49
How did you get -1/24 for lambda
Jooee Karwande
51:41
thank you
Joshua Kim
52:04
Cool thanks Prof Lucas!
