Muzzle velocities of eight shells tested with a new gunpowder yields the following results 2959 ft/s 2970 ft/s 2899 ft/s 2999 ft/s 3018 ft/s 2900 ft/s 3000 ft/s 2943 ft/s The manufacturer claims that the new gunpowder produces an average velocity of no less than 3000 ft/s. Does the sample provide enough evidence to contradict the manufacturer's claim? Use significance level of 0.05. Provide solution for testing the hypothesis.
