D) Pearson's correlation, linear regression

When analyzing the relationship between two continuous variables (years of formal education and number of books read per year), a parametric analysis would involve using Pearson's correlation coefficient. However, if the data violate assumptions of normality or equal variances, a non-parametric analysis would be more appropriate. In this case, a non-parametric alternative to Pearson's correlation coefficient would be Spearman's correlation coefficient, which does not rely on the assumptions of normality and equal variances. Therefore, the best choices for this question are A) Pearson's correlation and Spearman's correlation.
