Q2/ The speed of a file transfer from a server on campus to a personal computer at a student's home on a weekday evening is normally distributed with a mean of 60 kilobits per second(kbps) and a standard deviation of 4 khps. 1) What is the probability that the file will transfer at a speed of 70 kbps or more? 2) What is the probability that the file will transfer at a speed of less than 58 kbps? 3) If the file is 1 megabyte, what is the average time it will take to transfer the file? (Assume 8bits=1byte, and 1 mega = 1000 kilo)
