A tire manufacturer claims that its tires have a mean life of 40,000 kms. A random sample of 46 of these tires is tested and the sample mean is 38,000 kms. Assume that the populations standard deviation is 2,000 kms and the lives of fires are approximately normally distributed, with 5% level of significance. What is the critical value? What is the appropriate decision rule?
