I do have answers to these but I'm not sure how to work them out..

If you could help that would be great! :)

1st part:

A,B,C are schools. Is the choice of math programs followed independently by school? Write the hypotheses.

2nd part:

There is a table with X,Y,Z for rows and S,M,H for rows

XS:28,XM:44,XH:14

YS:20,YM:24,YH:17

ZS:51,ZM:66,ZH:20

show that this table has 4 degrees of freedom aand show that expected frequency for YM is 28.78 correct to 2 decimal places.

3rd part:

find the complete Chi-Square statistic..

(I want to know how to get the expected for each cell of the table)
