The second worksheet (in the Excel file linked below the exam) is the pdf of a random variable U, presented as a tabled probability distribution. This can be called a probability model of the random variable U in a population. Compute the population mean of the random variable U, given the probability model of it presented in the second worksheet. u P(u) 0 0.3 1 0.1 2 0.1 3 0.1 4 0.05 5 0.05 6 0.05 7 0.05 8 0.05 9 0.05 10 0.05 11 0.05
