Explanation / Answer

1)

expected count and the contribution to the chi-square statistic for the (Group 1, Yes) cell  

=row total*column total/grand total =102*257/382=68.6

contribution to the chi-square statistic =(O-E)2/E =(59-68.6)2/68.6=1.343

2)

expected count =287*129/545=67.9

contribution to the chi-square statistic=(77-67.9)2/67.9=1.220
