I have tried the formula for a test but I’m getting a different answer on excel 😩

Wasn't too clearly explained. Possibly little longer or shorter the video but with more context flushed out for the real world examples used to explain the concepts.

The formula is wrong right in the first half! Since, it should have been difference between sample means in the numerator and it should be sample standard deviation! not population, otherwise that would be a z test itself rightt!
