The mean mass of the puppies at five months is 4.31 kg. The masses follow the normal distribution. In an effort to increase their mass, a supplement is added to their daily meals. The subsequent masses of a sample of five-month-old puppies were (in kilograms): 4.28 4.23 4.25 4.27 4.57 4.33 4.21 4.35 4.50 4.29

a. At the 0.01 level, has the supplement increased the mean mass of the puppies? (Round the final answer to 3 decimal places. Negative answers should be indicated by a minus sign.) Value of the test statistic Reject H0 if t > . H0. There is evidence to conclude that the additive increased the mean weight of puppies.

b. Determine or estimate the p-value. (Round the final answer to 4 decimal places.)

two masses m1 = 4.70 kg and m2 which has a mass 50.0% that of m1, are attached to a cord of negligible mass which passes over a frictionless pulley also of negligible mass. If m1 and m2 start from rest, after they have each traveled a distance h = 2.90 m, use energy content to determine the following. (a) speed v of the masses (b) magnitude of the tension T in the cord

Suppose you have a system of two masses strung over a pulley. Mass 1 (6.2 kg) hangs on the right side of the pulley suspended over the ground at height 0.7 m. Mass 2 (2.3 kg) hangs over the left side of the pulley and rests on the ground. The pulley is a uniform disk of mass m and radius 12.5 cm. When the system is released, Mass 1 moves down and Mass 2 moves up, such that Mass 1...
