Write the answer on paper plz Suppose that a battery company

Suppose that a battery company is coming out with a new deluxe AAA battery that is supposed to last longer than its regular AAA battery. However, these new batteries are more expensive, so to justify paying the higher price, you would like to be convinced that they really last longer than the current batteries. Based on years of experiences, the current batteries last 30 hours of continuous use, on average. A random sample of 15 new batteries lasted an average of 33.9 hours with a standard deviation of 9.8 hours. Does this data provide evidence that these new batteries last longer on average? Calculate the 95% confidence interval for new battery life.
