Calculate the statistics below using the following data on a sample of the variable $X$:
Data ($X$ sample) = $\{9, -1, 7, 0, -2, 5, 4, 9, 5 \}$
Using the sample data, calculate: Mean; Median; Mode; Range; Variance; Standard deviation; Coefficient of variation.
What I have (Please Check):
Mean: $4$
Median: $5$
Mode: $5,9$
Range: $11$
Variance: $17.25$
Standard deviation: $4.153311931$
Coefficient of variation: Standard Deviation/Mean $=1.038327983$

It looks good to me!
Do your answers need to be rounded to a particular significant digit? (the last two computations, I'm referring to)...Seems you have a good grasp of this material.
