**Note:**You are welcome and encouraged to skip any questions that only assess SLOs which you have already maxed out (or have close to maxed out), as indicated in your grade report. (Because only the top two graded items count, the grade for each SLO there can only ever go up or stay the same, because at worst the exam mark is below the existing top two and gets dropped. Note, however that at least one of the top two must come from a quiz or exam, so even if you have two high marks, if they are both from homework assignments, then you do need to do those exam questions)

**HW10****Modified**Textbook Exercises. For the scenario described in each problem, do the following**instead**of what’s asked in the problem in the book**Plot**the data and report relevant descriptive statistics- (for the problems where there’s no “raw” data frame, you don’t necessarily have to create a plot, since this would require creating a data frame first; instead you can provide a frequency/relative frequency/contingency table. If using Markdown, you might want to have a look at Lab 8, where we filled out contingency tables, for formatting guidance)

**Define the parameter**of interest**with context**and using appropriate notation**State hypotheses**in words and in symbols**Check the conditions**for using an analytical approximation for the sampling distribution.- For the sake of practice, proceed with the analysis
**even if the conditions are not satisfied**. **Construct a confidence interval***without simulation*using the appropriate analytical approximation**Interpret**the confidence interval**in context**- Find the appropriate (standardized)
**test statistic** - Use the test statistic to
**find the P-value** **Interpret the test results in context**(use alpha = 0.05)

**List of Problems**- 6.58 (one proportion)
- C.62 (difference of proportions)
- 6.126 (one mean)
- 6.224 (difference of means)

**SLOs:**C1, C3, C4, D1, D4, D5, E3, E5**Note:**You are encouraged to write up this homework in an RMarkdown document (you can use one of the lab templates), since that way you will have a record of the steps you took and R will do the arithmetic and plotting for you, etc. However, this is not required — you can do the calculations another way if you choose. You can also mix and match if you want, and embed screenshots from StatKey in a Markdown document if you prefer to do that (see my solutions for Labs 7 and 8 for how to embed image files in Markdown). However, if you do use Markdown credit can also be earned for SLO D2.- In any case, turn in all files to
`~/stat113/turnin/hw10`
