Question

The figure below shows the relationship between parent nest size and offspring nest size for 100 parent-offspring observations of barn swallows, Hirundo rustica. The line is the least-squares-regression line. Note that the graph actually plots the logarithm of nest size, because nest sizes, like many measures of volume, are otherwise strongly skewed to the right. Below is a partial Excel regression output for these data.

What is the value of the test statistic? (Round your answer to two decimal places.)
