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 #498# km when the battery is fully charged.
The engineer collects a random sample of #43# new batteries and measures the performance of each one.
She plans on using a one-sample #t#-test to determine if the mean range of the new battery significantly differs from #498# km, at the #\alpha = 0.01# level of significance.
State the null and alternative hypotheses of the proposed test.
