Discrepancy between formulas and standard error

Regarding my last comment on the discrepancy between formulas given in the video and the standard error calculation in exercise solution, I am now sure that there is mistake in that solution because instead of using the pooled sample variance in the calculation of standard error, you had just taken a square root of the pooled sample variance there, but in the solution of this exercise, you used the correct formula.
