4.) The Ferris wheel at the landmark Navy Pier in Chicago takes 7 minutes to make one full rotation. The
height H in feet above the ground of one of the six-person gondolas can be modeled by:
H(t) = 70sin 2pi/7 (t - 1.75) + 80, where t is time in minutes. If you are loaded onto the gondola at 11 AM
how far off the ground will you be at 11:03?

1. there are 25 students who started computer programming in elementary school and 25 students who started computer programming in middle school. the first group had a mean final project grade of 95% and the second group had a mean final project grade of 92%. the line plot shows the differences after 10 rerandomizations. determine whether the difference in the means of the two groups is significant based on the line plot. explain your answer.
