Chapter 1: Overview and Descriptive Statisticsc. The following is a Minitab histogram of this data. The center of the histogram issomewhere around 2 or 3 and it shows that there is some positive skewness in the data.Using the rule of thumb in Exercise 1, the histogram also shows that there is a lot ofspread/variation in this data.RelativeFrequency.20.10.00012345678Number18.a.The following histogram was constructed using Minitab:800700Frequency6005004003002001000024681012141618Number of papersThe most interesting feature of the histogram is the heavy positive skewness of the data.Note: One way to have Minitab automatically construct a histogram from grouped datasuch as this is to use Minitab's ability to enter multiple copies of the same number bytyping, for example, 784(1) to enter 784 copies of the number 1. The frequency data inthis exercise was entered using the following Minitab commands:MTB > set c1DATA> 784(1) 204(2) 127(3) 50(4) 33(5) 28(6) 19(7) 19(8)DATA> 6(9) 7(10) 6(11) 7(12) 4(13) 4(14) 5(15) 3(16) 3(17)DATA> end8
