B. A manufacturer of car batteries claims that the life of the company's batteries is approximately normally distributed with a standard deviation equal to 0.9 year. If a random sample of 10 of these batteries has a standard devotion of 13 years, do you think that o> 0.9 year? Use level of significance 0.05. Using the five-step procedure results hint: (x² (0-8³²) x= Σ E 1. State the null and alternative hypothesis H 2. State the Level of significance/ degree of freedom 3. Use the appropriate test statistics 4. State the critical or rejection region 5. Make your conclusion and recommendation H:
