Ryan Sanders BUAD 310 – HW 2 a) Population is all compact automobiles in low-speed collisions Parameter is the average damage cost of all compact automobiles in low-speed collisions Sample is the 30 low-speed collisions being looked at Statistic is the average damage cost of the 30 collisions b) Variable of interest is the average cost of the damage for the low-speed collisions. This variable is quantitative. c) This variable is discrete d) mean = 44821/30 = 1494.03 median = (30+1)/2 = 15.5 (1267+1328)/2 = 1297.5 mode = 886 1 st quartile = 0.25*(n+1) = 7.75 (763*0.25) + (851*0.75) = 829 3 rd quartile = 0.75*(n+1) = 23.25 (1544*0.75) + (2048*0.25) = 1670 e) range = 4200 – 361 = 3839 variance = 1057902 standard deviation = 1028.54 interquartile range = 841 f) coefficient of variation = (s/x) * 100 = (1028.54/1494.03) * 100 = 68.84% g) Minitab printout h) middle 50 % 829 to 1670 upper 25% 1670 to 4200

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
