Use a t-distribution to find a confidence interval for the difference in means mu Subscript 1 Baseline minus mu Subscript 2 using the relevant sample results from paired data. Assume the results come from random samples from populations that are approximately normally distributed, and that differences are computed using d equals x Subscript 1 Baseline minus x Subscript 2. A 95% confidence interval for mu Subscript 1 Baseline minus mu Subscript 2 using the paired difference sample results x Overscript bar EndScripts Subscript d Baseline equals 2.4, s Subscript d Baseline equals 1.7, n Subscript d Baseline equals 30 Give the best estimate for mu Subscript 1 Baseline minus mu Subscript 2, the margin of error, and the confidence interval. Enter the exact answer for the best estimate, and round your answers for the margin of error and the confidence interval to two decimal places.

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?
