Thanks for the great videos, but I think for the second to last problem you can’t readjust the sample size to 40 to meet the n > 30 condition for normality because then you don’t meet the n < 10% of population condition for independence

In your second practice question you accidentally said it is a 1 mean z-interval when you mean 1 mean t-interval. Thanks for the great videos btw.
