Reading 11 Correlation and Regression - page 298 of Example relation, between, example

On page 298, Example 14 showed how to compute the t-statistic for the GM beta hypothesized parameter, which results a t-stat value of 0.8318 (using formula 10). However, later the example also states that in Table 9, the t-stat for Beta is 5.0795.
I wonder what the relation is between these two values. I thought they should be the same number..
Thanks in advance.
