7. Hypothesis Testing: One-sample t-test
One-sample t-test: Test Statistic and p-value
An engineer at Tesla is working on a new type of lithium-ion battery. It is known that cars with the old battery have an average range of km when the battery is fully charged.
The engineer collects a random sample of new batteries and measures the performance of each one.
She plans on using a one-sample -test to determine if the mean range of the new battery significantly differs from km, at the level of significance.
State the null and alternative hypotheses of the proposed test.
