What are the appropriate hypotheses to determine whether there is a d in attendance for shows on Tuesday evening and Wednesday evening?

Explanation / Answer

19)

here df(between)=education levels-1=3-1=2

hence df(within)=df(total)-df(between)=24-2=22

SS(between)=df(between)*MS*within)=2*1936=3872

SS(within)=S(ttoal)-SS(between)=4182

MS(within)=SS(within)/df(within)=190.09

F =MS(between)/MS(within)=10.18

  

option C is correct

source SS df MS F between 3872 2 1936 10.18 within 4182 22 190.09 total 8054 24
