Using independent random samples of Canadians with different marital status, an analysis of variance (ANOVA) has been conducted to investigate whether annual household income differs by marital status. The income variable should be considered as interval-ratio and has been measured as follows: (.6 for each multiple choice question for a total of 3 points) 1 No income 5 $15,000 to $19,999 9 $50,000 to $59,999 2 Less than $5,000 6 $20,000 to $29,999 10 $60,000 to $79,999 3 $5,000 to $9,999 7 $30,000 to $39,999 11 $80,000 to $99,999 4 $10,000 to $14,999 8 $40,000 to $49,999 12 $100,000 or more The results of the ANOVA are presented below.
