In a statistics activity, students are asked to spin a penny and a dime and determine the proportion of times that each lands with tails up. The students believe that since a dime is lighter, it will have a lower proportion of times it will land tails up compared to the penny. The students are instructed to spin the penny and the dime 30 times and record the number of times each lands tails up. For one student, the penny lands tails side up 18 times, and the dime lands tails side up 20 times. Let pD = the true proportion of times a dime will lands tails up and pP = the true proportion of times a penny will land tails up. Which of the following are the correct hypotheses to test the student’s claim?
H 0: p Upper D minus Upper P p = 0 and H alpha: Upper P Upper D minus Upper P p less-than 0
H 0: p Upper D minus Upper P p greater-than 0 and H alpha: Upper P Upper D minus Upper P p less-than 0
H 0: p D minus P p = 0 and H alpha: P D minus P p not-equals 0
H 0: p D minus P p = 0 and H alpha: P D minus P p greater-than 0
