What does the dotplot suggest about the 75 70 75 distribution of the high temperatures? 70 65 80 55 85 A dotplot consists of a graph in which each data value is plotted as a point (or dot) along a scale of values. Dots representing equal values are stacked. First create a frequency distribution with a class width of 5 and the class midpoints starting at 55. The frequency for each class midpoint is listed below. 55 60 65 70 75 80 85 l 2 3 2 3 2 1 To create the dotplot, list the categories horizontally and place the appropriate number of dots above each of the values.

    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.
