The range is calculated by subtracting the smallest value from the largest value in a data set. Since the sample mean is not given and there is no information about the distribution of the data, we cannot calculate the standard deviation. Therefore, we can only determine the range, which is simply the difference between the largest and smallest values in the sample data set. The largest value in the data set is 15 and the smallest value is 5, so the range is 15-5 = 10. Therefore, the correct choice is C)10.
