- A 6-foot sub valued at $25 is divided among five players (P1, P2, P3, P4, P5) using the last diminisher method. The players play in a fixed order, with Pl first, P2 second, and so on. I round 1, P1 makes the first cut and makes a claim on a C-pièce. For each of the remaining players, the value of the current C-piece at the time it is their turn is given in the following table: a.) What is the fair share for each player? Show your work in the space provided below. b.) What does player 2 do with the piece and why? c.) What does player 3 do with the piece and why? d.) What does player 4 do with the piece and why? e.) What does player 5 do with the piece and why? £) Who gets the piece at the end of round 2 and why is it that person? g.)

An SRS of 100 flights by Happy Airlines showed that 80 were on time. Let pS be the proportion of on-time flights for all Speedy Airline flights, and let pH be the proportion of all on-time flights for all Happy Airlines flights. Is there evidence of a difference in the on-time rate for the two airlines? To determine this, you test the hypotheses H0 : pS – pH 0, Ha : pS – pH 0. The P-value of your test is 0.0117. Which of the following is an appropriate interpretation of the P-value? a. If the on-time rates for the two airlines are equal, there is a 0.0117 probability of getting samples with a difference as far or farther from zero as these samples. b. If the on-time rates for the two airlines are not equal, the probability of getting samples with a difference as far or farther from zero as these samples is 0.9883. c.
