Underinflated or overinflated tires can increase wear and decrease gas mileage. A tire manufacturer tested tires for wear at different pressures. The scatterplot shows individual data points. To describe the correlation between pressure and mileage, which correlation should you use? Scatterplot of tire inflation Pearson correlation table and spearman correlation table Question 3 Select one: a. Spearman's : The data are not linearly related, so the non-parametric correlation is best b. Pearson's r: The coefficient is higher, indicating a better fit c. None of the above: Since the data are not linear, we can't find a correlation
