me:just wait till 3 man
fat jewish brah:why
me: so we can train together <3
fat jewish brah: its gonna get crowded then
me: we need to hypthosis test that
does the number of people follow a normal distribution?
do we know the variance
fat jewish brah: im not doing this now
me: if it doesn't follow a normal distribution should we do a wilconcox test or a sign test?
fat jewish brah: just go eat and we will go
Me: is the data pairwise?
if not should we assume the sample error is an accurate representation of the variance
shall we assume the variance of both times is the same?
H0: the mean of both times is the same
is this a 1 tailed test or a 2 tailed test
are we test is the mean at 3 > then the mean at 2 or just different
fat jewish brah: stop
me: H1: u3>u2
u is obv mew, but i dont have a latin keyboard
fat jewish brah: im gonna go at like 2:30 and do a bit of cardio beforehand
me: what significance level are we testing this hypothesis at by the way?
fat jewish brah: i told u im not doing this
me: im going to assume the date is pairwise so we'll just use Uz and Sz because its the most apprpriate
fat jewish brah: im headed to the gym now, bored
I reckon i'd use the wilconcox or whatever its called method because I wouldn't want to assume the data was normally distributed. Assuming it was normally distributed i'd make the assumption the data was pairwise because i'd measure the mean number of people at the gym at 2 and 3 on the same day.
