Question:
Consider the perimeter of a part in Example 5-32. Let X1 and X2 denote the length and width of a part with standard deviations 0.1 and 0.2 centimeters, respectively. Suppose that the covariance between X1 and X2 is 0.02. Determine the variance of the perimeter Y = 2X1 + 2X2 of a part. Compare and comment on the result here and in the example.
