Instructions for questions
- Include your name and the CI, Hypothesis Test or Sample Size assignment that you were given; I don't want to have to look-up the HT you were assigned.
- Pick 2 from questions 1, 2, and 3 to answer. For example, you can pick to do a Hypothesis Test and a Confidence interval that you were assigned, or a Confidence interval and a sample size, .... 2 out of the 3.
- Your write up for 2 of the 3 questions 1-3 should be no more than 1 page total; I won't grade anything after the 1stpage.
- The scenarios used in your write upsdo not have to be real but should match the type of data for the hypothesis test that you are assigned. For example, if you are assigned a one sample mean HT, you should come up with an example that uses continuous data.
Assignments for questions
Write a different example for each assignment that you pick. You do not need to make up data, but you do need to make up statistics and use these for the templates or sample size calculations. For example, if you are assigned a 1-sample mean for a confidence interval, you have to pick an example (could be related to your research, nor not), pick a sample size, mean, and standard deviation. With these calculate a 95% confidence interval and report all of this using mostly words - you do not need to include the template. Be sure to tell me what assignment your write up reflects - this is really important. Don't use examples from class notes - use your imagination and if that doesn't help, look for some published journal articles and grab some appropriate numbers and statistics from there.

4. The data file contains 62 observations and the variables age, male, hypo, hyper, and linWidth. This comes from the same data set that we used in class 2 weeks ago, but again, it is only some of the original data. Calculate summary statistics for each column (you decide what statistics are appropriate and informative) and then list some tests and confidence intervals that you would do if you are interest in whether linWidth is associated by hypo/hyper classifications and also whether age and male affect linWidth
5. Using your own words (and not the words of the journal article), interpret the results in Table 2 of this article for the 1st outcome, condition of the teeth is fair or poor for the unadjusted model and for the adjusted model but only down through the income variable (so include number of ACEs, age, sex, and income) in your write up.

(thanks to Saurabh Mankotia for finding this article!)
To summarize: You need to turn in answers to 2 of the 3 personal assignments for Q1-Q3. I will only grade up to 1 page of write up for these. Next, you need to do summary statistic calculations and report them for Q4 and then write about what methods you would use to analyze the data further. This should take about .5 page. And then for Q5, get the article and write a brief discussion of the results for the 1 outcome as described in Q5. This could be another .5 page.
