11. A sample of 30 used cars sold by an auto dealership in 2009 revealed that the correlation between selling price and number of kilometres driven was −0.45. We want to test, at the 1% significance level, if there is a negative linear relationship in the population between selling price and number of kilometres driven. According to the p-value given in the table, our conclusion would be to reject the null hypothesis and conclude that the sample evidence supports the...
