Round your answer to 4 decimal places ] E Indicate the correct decision and state appropriate conclusions p-value- ? Significance level, a:

Explanation / Answer

a)

as expected frequency =row total*column total/grand total

hence below i table for expected frequency::

b) Ho:.. are independent

Ha:..are dependent

claim: Ha

c)

distribution: chi square ; degree of freedom =(row-1)*(column-1)=(3-1)*(4-1)=6

d)

applying chi square test:

test statsitic =21.0668

e)

p value =0.0018

f)

signfiicance level=0.05

Ei=?row*?column/?total northeast South Central west skinny 65.790 56.979 69.608 59.622 Curly 78.322 67.832 82.867 70.979 Steak 79.888 69.189 84.524 72.399
