A tire producer wants to test whether the mean diameter of the tires produced on a given day equals 36 inches. Whether the mean diameter is less than 36 is of little or no importance, but it is important for the firm to determine whether or not the mean diameter is more than 36 inches. The firm chooses a random sample of 49 tires, and find that their mean diameter is 36.4 inches and the sample standard deviation is 0.8 inches. Should the firm accept the hypothesis that the mean diameter is 36 inches? Use alpha = 0.05. What is the null hypothesis? What is the alternative hypothesis? What distribution are you using? What test are you running? What is your conclusion?
