Question 1:
Part A: Draw an “ordered” Stem and Leaf Diagram displaying the data below. It will help if you set up some kind of tally chart.
In a large room of people, the age of each person was obtained.
Here are the data: 26, 43, 18, 42, 12, 65, 30, 18, 37, 23, 36, 47, 42, 16, 51,41, 29, 15, 29, 31, 47, 54, 41, 34,
43, 22, 50, 43, 38, 32, 46, 60
Part B: Draw a histogram displaying the ages.
Use the following information when drawing your histogram.
50-54, 55-59, 60-64, 65-69
Grades for Accounting 101 quiz. The data below gives the grades on an accounting quiz. The highest grade was a 90 and the lowest, a 20.
Grade | Number of Students Who Received That Grade |
20 | 2 |
50 | 5 |
60 | 7 |
70 | 13 |
80 | 4 |
90 | 1 |
Draw a bar graph for this distribution of grades.
Use the following information when making your graph.
Calculate the standard deviation of grades for Accounting 101 quiz. Note: You must do the calculation of the standard deviation as we did in class. Round final answer to the nearest tenth (1dp).
X | (X – x-bar) | (X – x-bar)2 | f | (X – x-bar)2 * f |
20 | 20 – 63.0 = -43.0 | (43.0)2 = 1849 | 2 | 3698.00 |
50 | 50 – 63.0 = -13.0 | (-13.0)2 = 169 | 5 | 845.00 |

Draw a bar graph for these data of the heights of women on a college soccer team. Use the following information when making your graph:
Calculate the standard deviation of the heights of women on a college soccer team. Note: You must do the calculation of the standard deviation as we did in class. Round final answer to the tenths place (1 dp.)
X | (X – x-bar) | (X – x-bar)2 | f | (X – x-bar)2 * f |
65 | 65-68.0=-3.0 | (-3.0)2= 9 | 1 | 9.0 |
66 | 66-68.0=-2.0 | (-2.0)2= 4 | 4 | 16.0 |
