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.
Q4: What is the computed value for t?
