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 and a standard deviation of 4 kilobits per second.What is the probability that the file will transfer at a speed less than 70 kilobits per second?
Given that P(Z<1) = 0.8413, P(Z<2.5) = 0.9938, P(Z> 2) = 0.0228
