The correlation between debts. Figure 2.4 (page 92) shows a strong positive relationship between debt in 2010 and debt in 2009 for 33 countries. Use the bootstrap to perform statistical inference for these data. DEBT (a) Describe the shape and bias of the bootstrap distribution. Do you think that a simple bootstrap inference (t and percentile confidence intervals) is justified? Explain your answer. (b) Give the 95% BCa and bootstrap percentile confidence intervals for the population correlation. Do they (as expected) agree closely? Do these intervals provide significant evidence at the 5% level that the population correlation is not 0?
