There are very few students with low GPA whereas large number of students have high GPA. From histogram and stem leaf chart we observe that the distribution is not normal. d) Select a second continuous variable that you believe would approximate a normal distribution In my view, Height in Inches may follow a approximate normal distribution. e) Create a graph to show its distribution.

Since all students are adults and their heghts are equally distributed around a mean value. Also from histogram and stem leaf chart we observe that the height is normally distributed. 3. Jonathan is a 42 year old male student and Mary is a 37 year old female student thinking about taking this class. Based on their relative position, which student would be farther away from the average age of their gender group based on this sample of MM207 students?

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.
