So on the FRQ#4 I did 2 sample z test for difference of mean instead of 2 sample t test cuz I thought if we has sample SD, we could use it😭. I wrote down all the 4 process steps tho

Im probably gonna major in atmospheric science, geoscience or smth related to meteorology and I just want to know which EC's could help me
