A popular automotive company has launched a new version of a sports car on the market, which supposedly has less gasoline consumption than the predecessor model. The producer states that the new model has an average consumption of 8 liter per 100 Km. the standard deviation of the consumption is assumed to be o = 1.2 liter and the average consumption in 50 test drives has been 8.5 liter per 100 km. i. Decide whether the information provided by the producer is credible. Use the hypotheses test Ho:µ = 8, H1:µ > 8 with significance level of 10% ii. Would the test decision be the same if the standard deviation of the consumption were o = 1.6 liter?
