Introduction to hypothesis tests for the population mean using ...
A company that manufactures batteries used in electric cars is reporting that their newest model of battery has a mean lifetime, µ, of 20 years. To test the
company's claim, a competitor has selected 39 of these batteries at random. The mean lifetime of the sample is 21.1 years. Suppose the population standard
deviation of these lifetimes is known to be 4.1 years.
Is there enough evidence to reject the claim that the mean lifetime of the newest model is 20 years? Perform a hypothesis test, using the 0.10 Jevel of
