#14. The process capability ratio, C, of a process is 1.05; At some point of time Cox was found to be 0.95, and the process mean was less than the desired mean. What is the value of Z(LTL) and Z(UTL) with respect to the current process mean. (Show all work and draw a rough sketch of the distribution to illustrate your reasoning) (15 points) #15. The following activities constitute the critical path of a project. Each activity is listed with two values in the parenthesis, the first is the mean and the second is the "standard deviation (please note that the variance is the square of the standard deviation) B(16,4), F (42,7), H(20,4). (HINT: you will need to construct the distribution of project time to answer the following questions.) What is the chance the will take longer than 90 days to complete?
