The Health, Aging, and Body Composition (Health ABC) study is a 10-year study of older adults. A research project based on this study examined the relationship between physical activity and pet ownership. The data collected included information concerning pet owner characteristics and the type of pet owned. Here is a table of counts of subject classified by pet ownership status and education level: Education level,Non-pet owners,Dog owners, Cat owners Less than high school,421,93,28 High school graduate,666,100,40 Postsecondary,845,135,99 Note that “Dog owners” and “Cat owners” designate individuals who own a dog only or a cat only, respectively. Individuals who own a dog and a cat are not included in this table. Analyze the data. Include numerical and graphical summaries as well as a significance test. Summarize your results and conclusions. My answer: X^2 (chi-square distribution) = 23.1468 df = (r-1) (c-1) = 4 P-value= 0.000118 However, I don't know how to summaries my answer. Please someone help me... I though chi-square is: Ho: there is no association between education and pet owned. Ha: there is association between education and pet owned. If so, P-value <0.05, we reject Ho and accept Ha. Is this correct?

what do you mean, summarize? just write it the way you have it. in words.
Your p-value is exceptionally small 0.0118% You clearly would reject the null hypothesis that education level has no affect on pet ownership.
