Q2. The duration of a construction activity was estimated to be in the range [2, 6] days with a most likely duration of 4 days. A construction engineer used the following symmetric density function to model the duration: fx(x) = for 2 ≤ x ≤ 4 for 4 ≤ x ≤ 6 2-12 Determine the (a) mean, (b) variance, (c) standard deviation, (d) coefficient of variation, and (e) skewness.
