Please complete "Time to Practice" problem #$6$ at the end of Chapter $13$ in the "Statistics for People Who Think They Hate Statistics" textbook. Be sure you indicate whether you're retaining or rejecting the null $($and whether that means urban and rural residents likely do or do not have the same attitudes toward gun control$)$ based on the results you get!

$2.$ Please calculate z$-$scores for the "Attitude" variable in Chapter $13,$ Dataset $3($which you just used for the previous problem$).$

As with the homework assignments, you may turn in this work in several ways: $(1)$ expand the R console window so your code and output are both visible and take a screenshot or photo to upload here, $(2)$ upload multiple screenshots or photos if your work spans multiple screens, or $(3)$ cut and paste the text in your Console window into Word and turn that file in here.
