At significance level α=0.10\alpha=0.10, determine if the null hypothesis should be rejected given the test statistic and p -value. 1 A manufacturer of automobile batteries claims that the average life of its best battery is 54 months. A consumer advocacy group believes that this might be incorrect. The test statistic is found to be -7.07 and the p -value is 0\approx 0.
