In а survey оf students аt а cоllege, 71 оut of the 160 female students and 18 out of the 148 male students indicated that they felt unsafe on campus at least one time over the last semester. Blank 1: Give the proportion of female students who felt unsafe at least once. Online, just give the answer as a decimal rounded to 3 decimal digits (for example, 0.541, but that's the wrong value). On your scrap paper, number this problem 2a and give the proportion as a fraction and use the proper notation to identify the sample proportion (include subscripts since we have it split up by sex). Blank 2: Repeat this for the proportion of male students who felt unsafe at least once. Online give the decimal answer to 3 digits and on the work sheet give the fraction and proper notation. *Note - be sure to submit the work sheet showing your proportions and notation as a pdf within 10 minutes of completing this quiz.
