QUESTION 5
During the Middle Ages, armies often used catapults to launch flaming projectiles at their enemies. Because of the inferior materials and manufacturing processes of the time, excessive variability in the weight of flaming projectiles could damage the arm of a catapult, thus leading to inaccurate launches. Because of this problem, most armies maintained a staff of quality engineers to inspect projectiles prior to their use. During the Hundred Years’ War, the English army applied the following hypothesis test to each shipment of projectiles they received.
They used a level of significance of 0.05 and a sample of size 20.
Data must come from a population with Normal distribution in order to perform this test.
True
False
Solution
The correct answer is , " TRUE "
Because the sample size is very small .And large sample theory test can not applied because the central limit does not hold ,so the assumption of normal distribution is required to perform the test.
