Basic Computation: Variance, Standard Deviation Given the sample data

x: 23 17 15 30 25

(a) Find the range.

(b) Verify that Σx = 110 and Σx2 = 2568.

(c) Use the results of part (b) and appropriate computation formulas to compute the sample variance s2 and sample standard deviation s.

(d) Use the defining formulas to compute the sample variance s2 and sample standard deviation s.

(e) Suppose the given data comprise the entire population of all x values. Compute the population variance σ2 and population standard deviation σ.
