: An automobile industry uses a particular brand of automobile
batteries that have their lifetimes approximately normally
distributed, with a mean of 3.5 years and standard deviation of 0.5
years. If a random sample of 29 batteries has an average life of
3.4 years. Test the hypothesis that μ = 3.5 years against the
alternative, μ ≠ 3.5 years. Use 0.05 level of significance.
