Those with negative attitude were stratified as follows:15 youth,6 medium adults and 5 elderly. (i) Sketch a 3 by 2 contingency summary of this data (ii) State the hypothesis of this data, giving your α-level and degree of freedom (iii) Prove/ disapprove if there is any significant association between attitude regarding compulsory putting on of masks wherever in public
