For homework you need to study the vocab list below for Monday's test. It will be 20 words (matching), and there will be 3-5 additional questions. One of these will likely be to create a table showing the correct population parameter/sample statistic symbols for categorical and quantitative data. There will also be an additional questions chosen from the following: the definition and interpretation of a p-value, the steps for a hypothesis test, the differences between hypothesis tests/confidence intervals, and the goals of hypothesis tests/confidence intervals. The vocab list is below.
Sampling Distribution
Central Limit Theorem
Standard Error
Conditions/Assumptions:
10% Condition-->independence
Randomization-->generalization
Success Failure-->large enough sample (for Normal Model)
Confidence Interval
Margin of Error
Critical Value
Null Hypothesis--what we assume to be true
Alternative Hypothesis
One vs. Two Tailed Test
PValue
One Proportion ZTest
One Proportion ZInterval
Proportion (used for categorical data)
Mean (used for quantitative data)
p vs. p hat
xbar vs. mu
Diminishing Returns
Alpha Level
Statistical Inference
Interpret CI vs. meaning of _% confidence
Sampling Variability
Population Parameter
Sample Statistic
Sample Size
In addition, you have one homework question:
If you are going to the doctor to be tested for cancer, write your null and alternative hypotheses. Then, define a Type I and Type II Error. Finally, explain which type of error is worse and why.
