I have a data set for MLB teams. the assignment is to form a hypothesis based on the set.
h0- Teams with higher attendance will have a better ERA
h1- attendance will not effect the ERA
Preform a 5 step hypothesis test and show work for z and t test. I am not sure what kind of z or t test to run to get my answer?
I don't know what you mean by a "five step hypothesis test."
Ho = no effect (null hypothesis)
H1 = mean for low attendance is significantly different from mean for high attendance
You want Z for difference between means.
Z = (mean1 - mean2)/Standard error (SE) of difference between means
SEdiff = √(SE1^2 + SE2^2)
SE = SD/√n
I hope this helps.
