\\v . .w my, Mr. Moore's physics class built different-shaped parachutes to see which shapes were more effective. The smdenm tested the parachutes by dropping them from a height of 30 feet and timing the fall. They calculated the summary below: Mean so: Dev Mln D1 Medlun as Max 5.6secs 0.6sec 3.3secs 4.5 secs 4.8secs 5.2 secs 7.8 secs The smdenm wanted to see what happens to their times when they drop the parachutes from 45 feet. They find that every drop is increased by 2.5 seconds. Find the new mean and standard deviation. ,_ Mean, 13.1 seconds; standard deviation, 0.6 second ,_ Mean, 5.6 seconds; standard deviation, 3.1 seconds ,_ Mean, 5.6 seconds; standard deviation, -1.9 seconds ,_ Mean, 8.1 seconds; standard deviation, 0.6 second Question 2(Multiple Choice Worth 4 points) (01.05 MC) The salaries, in thousands of dollars, of all individuals employed at a shipping company are depicted in the boxplot below: 2n an to so 50 7n :0 an we 1m What is the interquartile range (IQR) of the salaries? ._ 25 .35 ._ 70 ._ 100
