Mr. jenning's physics class built different-shaped parachutes to see which shapes were more effective. the students tested the parachutes by dropping them from a height of 25 feet and timing the fall. they calculated the summary below:
mean std dev min q1 median q3 max
4.2 secs 0.5 sec 2.6 secs 3.4 secs 4.0 secs 5.7 secs 6.8 secs
the students want to see what happens to their times when they drop the parachutes from 35 feet. they find that every drop is increased by 1.5 seconds. find the new mean and standard deviation.
