I'm having a problem with the entire Chi-square thing..
I do have answers to these but I'm not sure how to work them out..
If you could help that would be great! :)
A,B,C are schools. Is the choice of math programs followed independently by school? Write the hypotheses.
There is a table with X,Y,Z for rows and S,M,H for rows
show that this table has 4 degrees of freedom and show that expected frequency for YM is 28.78 correct to 2 decimal places.
find the complete Chi-Square statistic..
(I want to know how to get the expected for each cell of the table)
X^2 = Σ[(O-E)^2/E]
E = (row total)(column total)/(grand total)
