4) Elon Musk announced Teslas would soon be powered by a battery with a lifespan of more than 1 million miles. Elon Musk: "The current battery pack is about maybe 300,000 miles to 400,000 miles.... And the team says the results from tests on the battery are "far superior" than other lithium-ion batteries. An independent lab claims that the mean lifetime of the lithium batteries is greater than 300,000 miles. The lab selects 30 of these batteries and finds the mean lifetime to be 305,000 miles with a standard deviation of 8000 miles. Test the manufacturer's claim. Use =0.05. Round the test statistic to the nearest thousandth. a) Hypothesis: b) Critical value (tcritical): c) Test statistic (tstat) and the decision about the test statistic: (reject or fail to reject Ho) : d) The conclusion that results from the decision about Ho, how would you address the manufacturer's claim?
