    "A quarterback for the seattle seahawks completes 54% of his passes" so P(completion) = 0.54 we can use the random number table to simulate the quarterback throwing the football

    Rule: if the number is between 00 and 53 (inclusive), then we have a success. The pass worked if the number is between 54 and 99 (inclusive), then we have a failure. The pass didn't work

    no, he made 20 attempts so pull off 20*2 = 40 digits (each in pairs)

    very good. The experimental probability is 40% or 0.40 while the theoretical probability is 54% or 0.54 so ideally, if he attempted more passes, then the experimental probability should get closer and closer to the theoretical probability

    or... there is the possibility some error happened somewhere, or that his throwing style changed or something. it's possible he could throw worse as time wears on. If that's the case, then the population proportion would decrease over time
