In a standardized IQ test from question three scores are normally distributed with a mean score of 100(u=100) and a standard deviation of 15(o=15) if one individual from this population is randomly selected what is the probability that his or her IQ score is greater than 107 if a random sample of 16 people is selected from this population what is the probability that the mean IQ score of the sample is greater than 107 is this unusual event?

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
