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 = 0.01 level 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 o be the mean height reached by players wearing their old sneakers, be the mean height reached by players wearing the new sneakers, and d = N - o. Assume that the jump differences have a normal distribution. (Round your results to three decimal places) Which would be correct hypotheses for this test? Ho d = 0, H: d > 0 : Ho d = 0, H: d < 0 O Hod : 0, H: d = 0 Hod > 0, H: d < 0 O Hod = 0, H: d 0 Maximum Height reached (inches): wearing old shoes wearing Jumpalicious shoes 32 42 32 33 34 41 34 30 30 41 32 43 40 33 32 40 32 37 39 39 30 44 29 42 29 40 29 30 31 31 37 40 Test Statistic: Give the P-value: 0.002 Which is the correct result: Reject the Null Hypothesis Do not Reject the Null Hypothesis Which would be the appropriate conclusion? There is significant evidence to suggest that the new sneakers will help players jump higher. There is not significant evidence to suggest that the new sneakers will help players jump higher.
