BUAD 310 Minitab Project 4 1. a.) I see that the histogram is not symmetrical so that is why I would choose Chebyshev’s rule. b.) (minitab) The range is the least robust and the IQR is the most robust c.) The lower bound has negative values so we make it zero and in this case it would be (0, 3.219). The empirical rule is a better estimate in this case 2. a.) The normal sample will be the most volatile because its mean is closest to zero

    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.
