Pleаse nоte thаt this questiоn cоnsists of six pаrts. You may use MINITAB to double check your final answer. However you MUST show all the mathematical work to get to the final answer. Just giving the answer without adequate work/explanation may result in zero for the question. Manufacturer of an electric vehicle company claims that on average battery last for 340 miles on a full charge. Recently, the company has been getting many complaints about need for charging of the vehicles in less than 340 miles. Company would like to see if the true average mileage could possibly be well short of their quoted claim. They have collected data from a random sample of 51 electric vehicles manufactured by their company. Average mileage per charge for the sampled vehicles was 330 miles with a standard deviation 25 miles per full charge. Set up the appropriate null and alternative hypotheses for testing the company’s question to address the customer complaints. Make sure to use proper notations when setting up and . Are the conditions to carry out the above stated test are satisfied? If the conditions are satisfied, explain how they were satisfied for this problem rather than simply giving a "yes" or "no" answer. Calculate the test statistic. Show your calculations. Calculate the p-value for the test. You may use MINITAB to find the numerical value of the p-value for the test. However, you MUST clearly write down the probability statement. Write the final conclusion in the context of the problem (use 5% significance level). Instead of doing the above hypothesis test, suppose the company wanted to obtain an interval estimation for the true proportion of vehicles that does not last for 340 miles from a full charge. In the sample of 51 vehicles, battery did not last for 340 miles on full charge for 38 vehicles. Obtain a 95% confidence interval for the true proportion of vehicles that does not last for 340 miles in a full-charge.
