A new shoe company claims that their new Jumpalicious sneakers will help all wearers jump significantly higher. A group of basketball coaches wish to test this claim at the a = 0.05 tevel of significance. A random sample of players jumped with their current sneakers on, the maximum height reached was recorded, then the same group of players put on the Jumpalicious sneakers and jumped again, recording the maximum height reached. The 'old shoe' and new shoe' data is given below. Let Ho be the mean height reached by players wearing their old sneakers, µn be the mean height reached by players wearing the new sneakers, and H = HN - Ho. Assume that the jump differences have a nomal distribution. (Round your results to three decimal places) Which would be correct hypotheses for this test?

Transcribed Image Text:A new shoe company claims that their new Jumpalícious sneakers will help all wearers jump significantly
higher. A group of basketball coaches wish to test this claim at the a = 0.05 tevel of significance. A
random sample of players jumped with their current sneakers on, the maximum height reached was
recorded, then the same group of players put on the Jumpalicious sneakers and jumped again, recording
the maximum height reached. The 'old shoe' and new shoe' data is given below. Let Ho be the mean height
reached by players wearing their old sneakers, uN be the mean height reached by players wearing the new
sneakers, and 4 = EN - Ho. Assume that the jump differences have a normal distribution. (Round your
results to three decimal places)
Which would be correct hypotheses for this test?
O Ho: p4 + 0, H:µa = 0
Ho: H4 = 0, H1 :Hd > 0
Ho: H4 = 0, Hị :Ha 0
Ho: 4 > 0, H1 : Hd < 0
O Ho: H4 = 0, H:Ha < 0
Maximum Height reached (inches):
wearing old shoes
wearing Jumpalicious shoes
