This should help you. I do not want to give you the answers. I want you to do them yourself with the instructions I gave you and then come back and post them when you are done so I may check them. Okay?
Mean: [tex]\bar{x} = \frac{x_{1} + x_{2} + x_{3} + x_{4} + x_{5} + x_{6} + x_{7}}{n}[/tex]
[tex]\bar{x} = \frac{42 + 61 + 13 + 9 + 12 + 42 + 62}{7}[/tex]
[tex]\bar{x} = \frac{241}{7}[/tex]
[tex]\bar{x} = 34\frac{3}{7}[/tex]
Median: 9, 12, 13, 42, 42, 61, 62
42
