Consider a situation that is similar to that in one of the video lectures, i.e., Alice observing Bob traveling from Earth to a star at a certain distance from Earth. Assume that the Lorentz factor for the relative velocity between Alice’s frame of reference (the Earth-star frame of reference) and Bob’s frame of reference (the spaceship frame of reference) has a value of 4. From Bob’s perspective, he’s at rest and he sees the star rushing toward him. The elapsed time on Bob’s clock between the time Earth passes him and the star passes him is 12 years. How much time does he observe elapse on one of Alice’s clocks?

John Datum is another customer of the same wireless company. Just like our consultant, John is trying to compare the old plan and the new plan. Having looked at his past monthly data usage values, John, unlike our consultant, has decided to use a simple scenario approach to model his future data usage. In particular, John estimates that his monthly data usage Ū (in GB) can take one of three values, Ū1 = 15, Ū2 = 21 and Ū3 = 24, each value being equally likely (i.e., each having a probability of 1/3 associated with it). What is the expected value of John’s monthly payments, in $, under the old plan?
