(01.05 MC) Mr. Mооre's physics clаss built different-shаped pаrachutes tо see which shapes were more effective. The students tested the parachutes by dropping them from a height of 30 feet and timing the fall. They calculated the summary below: Mean Std Dev Min Q1 Median Q3 Max 5.6 secs 0.6 sec 3.3 secs 4.5 secs 4.8 secs 5.2 secs 7.8 secs The students 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. (4 points)
