Question1

What test can be used to evaluate the mean HgbA1c 1 year before vs. mean HgbA1c 1 year after use of insulin pump? Perform this test and report a two tailed p-value. Also give a 95% Cl for mean difference in HgbA1c before minus the mean HgbA1c after use of the insulin pump.

Question2

Mary and Sally are in a foot race. When Mary is 22 m from finish line, she has a speed of 4.0 m / s and is 5.0 m behind Sally, who has a speed of 5.0 m / s. Sally thinks she has a simple win and so, throughout the remaining portion of the race, decelerates at a constant rate of 0.50 m/s2 to finish line. What constant acceleration does Mary now require during the remaining portion of the race, if she wishes to cross finish line side-by-side with Sally?
