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.)
t =  

Regression Statistics Multiple R 0.7229 R Square 0.5226 Standard Error 0.1396 Observations 100

Explanation / Answer

t stat for intercept=beta0/SE(beta0)=0.5764/0.1542=3.74

t stat for Parents=0.6762/0.0653=10.26
