8. (10 points). Assume that there is a repeated task for project duration. Based on historical data, it takes 17 hours for the initial unit of output. The learning rate from the experience is 0.8. What is the time estimated for the 5 th task? Use following formula. Show all your work to get a full credit. Yx=aXb Where: Yx= time required for the x unit of output a= time required for the initial unit of output X= the number of units to be produced b= learning curve slope =log( learning %)/log(2)
