STAT 3743 Daily Outline
Up there should be four (4) files:

STAT3743_xxxxxx.3gp
(video for mobile phones) 
STAT3743_xxxxxx.ogv
(video in Ogg format) 
STAT3743_xxxxxx.pdf
(scanned lecture transcript) 
STAT3743_xxxxxx.webm
(video in WebM format)
The WebM
video is definitely the highest quality, but
you need a compatible browser/player to watch it.
See How to watch the video for instructions to get one.
Basic hypothesis testing procedure
 set up hypotheses, collect some data
 assume null is true, construct 95% CI for parameter
 if CI doesn't cover null value, reject H0, otherwise, don't reject
More terminology
 Type I error, Type II error
 significance level
 rejection region
 twosided and onesided tests
Tests of hypotheses for one proportion (asymptotic)
Draw pictures
Example: observe bunch of shotguns, do hypothesis test
Example: do another hypothesis test, but for different significance levels
pvalue of a hypothesis test
Example: find pvalue for previous test
Hypothesis testing: "reject H0 if pvalue is small"
Tests of hypotheses for two proportions
For one mean and/or one variance
Given SRS(n) from norm
, unknown mean
For means
 σ known: ztests for one mean
 σ unknown: ttests for one mean
If σ unknown but n is large then use ztest
Example: SRS(9) from norm
, hypothesis test for the mean, find pvalue
