2. A recent article stated that car owners drove an average of 3500 miles between oil changes last year. A random sample of 26 cars getting an oil change found a mean distance of 3375 miles since the last oil change with a standard deviation of 225 miles. Is this sufficient evidence to show the mean travel distance between oil changes has decreased? Identify the appropriate null and alternative hypotheses. . A. H:u= 3500 H: 3500 Β. Η, :μ= 3500 H, :μ< 3500 C. H, :μ= 3375 H, :μ< 3375 D. H:u= 3500 Hu> 3500
