Ariel dropped a golf ball from her second story window. The ball starts form rest and hits the sidewalk 1.5 seconds later with a velocity of 14m/s. Find the avarage acceleration of the golf ball
A lightbulb manufacturer regularly advertises that his bulbs last for at least 900 hours with
a standard deviation of 75 hours. A random sample is chosen before each campaign to
make sure that the claim is correct. If one such sample of 20 bulbs shows a mean of 925
hours, can the advertising claim be considered true at 0.05 level of significance?
Step Solution
1. State the null and alternative hypothesis
concerning the population mean, μ and the
type of test to be used
2. Specify the level of significance α
3. State the decision rule.
4. Collect the data and perform calculations.
5. Make a statistical decision.
6. State the conclusion.
