1. A MRT (Metro Rail Transit) car, 5km distance from Taft Station takes 100A over hard drawn copper trolley wire having a resistance of 0.270 per km. The rail and ground return wire have a resistance of 0.060 per km. (a) If the station supply voltage is 550V, what is the receiving end voltage at the car side? (b) If a line to ground fault occurs at the supply voltage causing a very high current of 500A, what is the new receiving end voltage at the car side?

A cable TV company was interested in making its operation more efficient by cutting down on the distance between service calls while still maintaining at least the same level of service quality. A treatment group of 18 repairpersons was assigned to a dispatcher who monitored all the incoming requests for cable repairs and then provided a service strategy for that day’s work orders. A control group of 18 repairpersons was to perform their work in a normal fashion—that is, by providing service in roughly a sequential order as requests for repairs were received. The average daily mileages for the 36 repairpersons are recorded in the table below. a. What are the populations of interest in this study?b. What is the level of significance of your test?c. Is there significant evidence that the treatment group had a smaller average daily mileage than the control group? Use α = 0.05
