Sheldon is the manager for Kara Tyres. He suspects that the claim that their tyres can go the minimum of 13800 km without being worn out is incorrect. He is going to address this issue in his annual report. He has sampled a group of 25 tyres, and calculated that the average kilometers that his sample of tyres can go before being worn out is 13690, with the sample standard deviation of 110 km. What should Sheldon write in his annual report at 0.01 significance level?
