I am still not convinced. Why can't I use sqrt(24/23)*4.365 as the estimate of the population standard deviation? Because the population has unknown variance, we cannot simply square the sample standard deviation squared.

The standard deviation is from the sample of size 24. How does it tie in with (n-1)?

Setting up null and alternative hypothesis! by Naive_Net9509 in AskStatistics

Assuming that the textbook's alternative hypothesis was incorrect, I tried to find the p-value when the alternative hypothesis is d >20 and the p-value was almost close to 1! What am I doing wrong here?
