Table is from a longitudinal study of coronary risk factors in schoolchildren(Woolson and Clarke 1984). A sample of children aged 11-13 in 1977 were classified by gender and by relative weight (obese, not obese.)in 1977, 1979, and 1981. Analyze these data.

TABLE Data for Problem

Gender				Responsesa
Gender	NNN	NNO	NON	NOO ONN		ONO	OON	OOO
Male	119	7	8	3	13	4	11	16
Female	129	8	7	9	6	2	7	14

1. Complete a preliminary analysis of the data

2. Determine the inter-rater reliability for both males and females comparing the first two time periods and comment.

3. Is there a difference in the proportion considered obese in the first to second time period for both males and females?

4. Is there a difference in the proportion considered not obese in the second to third time periods for both males and females?

5. Is the information that you have in parts c and d enough to draw conclusions about the time variable? Explain your answer.
