if a team of people is asked to construct two paper aeroplanes one from A4 sheet and the other from A5 sheet and test their flights performance. in this context the flight performance means the distance the planes fly when thrown normally measured from the point of release till the point plane first touches the ground.
Your excersise is to test four hypothesis by recording the distance flown over 30 trials for each plane.
part 1 large plane only
Flight data for previous batches of ur institute have been recorded overt he years the mean of the flight distance for A4 plane is 18 feet.
1. which test would we use to test the hypothesis stated in section 2 below? also state the statistical assumptions under which your test is valid
2. TEst the following pair of hypothesis at a level of significance at 2%.
Ho: Mean=18 feet where mean is the population mean of flights undertaken by the plane built by you.
H1: meanis not equal 18 feet
