My Ho is that something is not not not not true, but my Ha is that it is not not not true, but there is a Type 1 error
Obviously, we assumed not not not true but it was not not not not true
yo gurt
not not not not not not not not not not not not not not not not not true
what

What is the margin of error for a confidence interval of a proportion?
Gotta be 5
p+/-z*√((p(1-p))/n)
z*√((p(1-p))/n)
√(z)1-p(pn)
4
If my confidence interval overlaps zero what does that mean?
You did it wrong
The proof is in the pudding
No proof that there is difference

At what point do you consult the holy table a?
Never - calculator gang unite
Click here to get the question wrong
Every question - praise table a
when I need to check the proportion for my z-value
6
What are the symbols for population proportion and sample proportion?
Click here to get the question wrong
P = pop p = samp
p = pop p̂ = samp
P = pop p̂ = samp
7
General formula for finding the test statistic?
(sample statistic - populatlon parameter)/standard error
(sample statistic - population parameter)/standard eror
(sample statistic - population parameter)/standard error
(sample statistic - population parameter)/standerd error
8
How do you know that the samples were randomly selected?
I put all my faith into College Board being correct
If they aren't I'm cooked
Wait why was blue correct last time?
trust me bro (source: me)

Alex lacks confidence in his ability to perform a significance test without a Type 1 error, how do we help bro?
Pivot to Type II errors
Set significance level to .01
Tell him to drop AP Stats
100 Alex's vs 1 gorilla

What did you get on AP Statistics exam?
No comment (>3)

Why do we use the 10% rule?

So we can assume a binomial distribution

Who is "we"?

So if you have a probability and it wants to know if it its, like, significant, like how?
Put it in some rice
Testing the zzz
z-test for proportion
z-test for pro-portion
13
What is a short hand to checking np>=10 and n(1-p)>=10?
fails/successes^2 + 1-fails >=10
Checking if the # fails and # successes are >= 10
No need, I already locked in the 5
Not doing it

Yo!! Gurt is here. He wants to know who took his water bottle cap. What's the standard signicance level that its Joseph?
Not my boy Joseph he would never

How far can we generalize the findings if we find convincing evidence for Ha? You have 5 seconds
Only to the group from which the participants were sampled
Number of participants - 1
Rows - columns
To the entire population of the sample which population in the - I give up
16
A t-test for proportions comes back with a p-value of .02 with a significance level of .05, reaction?
According Unit 6 section 3 part 2.E, there is evidence for the hypothesis
Idk bro put the 2 in the bag
Seems legit
Oh no no no no, is that a t?!?
