Formulae for Statistics ࠵? = ࠵? ࠵? ࠵? = ࠵? ∙ ࠵? ࠵? ࠵? = ࠵? − ࠵? ( ࠵? − 1 ࠵? = ࠵? − ࠵? ࠵? Consider the set of test scores shown below: 88 82 95 71 91 95 86 83 76 58 83 96 92 86 94 90 94 61 71 72 99 92 83 50 84 89 87 66 99 99 96 84 73 72 70 59 92 93 95 1. a. Organize the data into a frequency table. Use classes of width 10, starting with 50. Include columns for both the frequency and the relative frequency. b. Use the frequency distribution in part (a) to create a frequency histogram of the data. Remember to give your chart a title and to label your axes. Consider the set of ages of students shown below: Ages ( x ) Frequency ( f ) 17 2 18 4 19 7 20 6 21 2 22 3 25 2 26 3 32 1 Total

    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.
