Incorrect results in Table 5.1.4 R code: independent t-test #25

This site is fantastic - please can I share a couple of minor errors:

In the table, the degrees of freedom for the t test are showing as 48, instead of 98.

The confidence intervals are also mismatching, but I can make them match exactly if the linear model CIs on beta_1 were used (if the directionality were reversed on either the t-test or the lm).

Thank you!
