The sample standard deviation was 3645.94 kilometers and n = 16. (a) can you conclude, using α = 0.05, that the standard devia- tion of tire life is less than 4000 kilometers? state any nec- essary assumptions about the underlying distribution of the data. find the p-value for this test. (b) explain how you could answer the question in part (a) by constructing a 95% one-sided confidence interval for α.
