At Rachel's 11th birthday party, 8 girls were timed to see how long (in seconds) they could hold their breath in a relaxed position. After a two-minute rest, they timed themselves while jumping. The girls thought that the jumping would not affect their times, on average. Test their hypothesis at the 5% level. Relaxed time (seconds) Jumping time (seconds) 29 21 49 43 29 29 22 21 23 25 45 43 37 35 29 32 NOTE: If you are using a Student's tdistribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) .WhathlJ'Je/g-value? (Round your answer to four decimal places.)
