This assignment requires the same data sets used in HW6.·Use theTdistribution for all problems involving means. Uset.testfor any problems with raw data.·For all hypothesis tests, be sure to state the null and alternative hypothesesusing symbols, the value of thetest statistic (includingdfif applicable), thep-value, the decision, and a conclusion in the context of theproblem. You do not need to calculate or report critical cut off values.
Roundt-scores and CIs to two decimal places. Reportp-values to four decimal places.·In Rmarkdown you can use $\mu$ to getor $\mu_{1}$ to get1, or use $p_{T}$ to get, for example.You can use this same notation to specify the null and alternative, such as $H_{0}: \mu_{1} = \mu_{2}$versus $H_{a}: \mu_{1} \ne \mu_{2}$, where thus use of \ne gives≠.You can also just use notation likemu[1], H0, Ha, != for not equal, etc.·When code is required, put all the code for a given problem in a chunk and then putALLthe writingAFTERthe chunk. That means any stated hypotheses would go after the code chunk for the problem. Wewant all the writing in one place and will not read writing before the code chunk.

First identify if the given statement is a statement about the nullor alternative hypothesis. Then write out the hypotheses using symbols (0.5 points each)
