A tire manufacturer has been producing tires with an average life expectancy of 25,000 kilometers. The company has recently redesigned its tires and they believe that the newly designed tires have a longer life expectancy. To test this claim, the company has taken a sample of 75 tires and recorded the life expectancy of each tire in the sample. The sample has a mean of 25,339 kilometers and a standard deviation of 1856.99 kilometers. At the 5% significant level, determine if the life expectancy of the tires has increased.
