# Question

The number of incidents in which police were needed for a sample of 10 schools in Allegheny County is 7, 37, 3, 8, 48, 11, 6, 0, 10, 3. Are the data consistent or do they vary? Explain your answer.

Find the range, variance, and standard deviation unless the question asks for something different.

Assume the data represent samples, and use the shortcut formula for the unbiased estimator to compute the variance and standard deviation.
