(this problem requires some supporting work with good notation for proportions written on your work sheet)  A survey was done on a sample of randomly selected students at a university.  Out of the 60 graduate students surveyed, 37 owned a vehicle.  For undergraduates, 68 owned a vehicle out of the 150 students sampled.  Blank 1:  Online, in blank 1, type in the proportion of graduate students who own a vehicle rounded to the nearest thousandth (so for example 0.761 although that is the wrong answer).  On your work sheet, give the proportion as both a fraction and as a decimal and be sure to use proper notation to identify it, including a subscript. (hint: sample or population prop?) Blank 2:  Do the same as blank 1 but for the undergraduate students.  Blank 3: Give the difference between the sample proportion of graduate students and the sample proportion of undergraduate students who own a vehicle as a decimal rounded to the thousandths place online.  On your work sheet, show this value and also the proper notation for this difference.

(work on your scrap sheet here is optional, but without the work there can be no partial credit.  If you’d like to show work by giving the proportions as fractions first and then as decimals on your work sheet, please do) A company sells t-shirts online and in their retail locations. Some shirts needed to be exchanged for another size.  Use the two-way table below to find the following proportions (online, give each one as a decimal rounded to the thousandth, so for example 0.238 and please show that 0 before the decimal point.  shirt kept shirt exchanged total retail purchase 1358 210 1578 online purchase 875 452 1327 total 2233 662 2895 Blank 1) Overall, what proportion of shirts were exchanged? Blank 2) What proportion of the shirts purchased in retail locations had to be exchanged? Blank 3) Of the shirts that were exchanged, what proportion where purchased online?
