Confidence Intervals for Proportions
Estimate +- "Margin of Error"
What is the formula for a confidence interval?
The starting hypothesis to be tested
What is the null hypothesis H_0 ?
sqrt((hat p hat q)/n)
What is the standard error for the sampling distribution?
It contains all the values of the parameter that we'd consider plausible if we reject the null hypothesis
What is the alternative hypothesis H_A ?
The number of standard errors to move away from the sample statistic to specify an interval that corresponds to the specified level of confidence
What is the critical value?
The probability of seeing data like these (or something even less likely) given that the null hypothesis is true
What is the P-value?
z * sqrt((hat p hat q)/n)
What is the formula for the margin of error?
A way to proceed when there is no obvious sampling distribution model to use, and there may be no data available
What is a simulation?
hat p +- z * SE(hat p)
What is the formula for a confidence interval?
The difference between the value you see in your data and the value in the null hypothesis
What is the effect size?
