A sample of six resistors yielded the following resistances (ohms): x1 = 45, x2 = 38, x3 = 47, x4 = 41, x5 = 35, and x6 = 43.

(a) Compute the sample variance and sample standard deviation.

(b) Subtract 35 from each of the original resistance measurements and compute s2 and s. Compare your results with those obtained in part (a) and explain your findings.

(c) If the resistances were 450, 380, 470, 410, 350, and 430 ohms, could you use the results of previous parts of this problem to find s2 and s?
