The battery manufacturer that makes the batteries for the municipal police department’s body cameras asserts its lithium batteries last at least 16,000 hours. You sample 200 batteries and find that the X̅ =13,000 hours and s = 600 hours. Should the company’s claim be rejected? Will you use a one-tail test or a two-tail test? Why? Test at α = 0.05.

A battery manufacturer advertises that the mean reserve capacity of a certain battery is 1500 hours. You suspect that the batteries’ reserve time is less than the advertised value. To test this claim, you randomly select a sample of 20 batteries and find the mean reserve capacity to be 1320 hours. Assume that the population standard deviation is 320 hours. Do you have enough evidence to support the manufacturer’s claim? What assumption is necessary for this test to be valid?...

A cell phone manufacturer claims that the batteries in its latest model provide 20 hours of continuous use. In order to verify this claim, and independent testing firm checks the battery life of 100 phones. They find that the batteries in these 100 phones last an average of 19 hours with a standard deviation of 5 hours. Conduct an appropriate hypothesis test to check whether the results from this sample provide sufficient evidence that the true mean battery life is...
