You are involved in a study of the relation between smoking and cholesterol concentration of high-density lipoprotein cholesterol (HDL-C), the following data were collected from samples of adult males who were non-smokers, light-smokers, moderate smokers and heavy smokers. Moderate Heavy Light Smokers Smokers Smokers Smokers Non- 12 9 3 10 8 4 11 11 9 9. 9 9 5 4 9 10 7 12 8 You wish to know if these data provide sufficient evidence to indicate that the four populations differ with respect to mean concentration of HDL-C. Let the probability of committing type I error be 0.05. If an overall significant difference is fount, determine which pair of individual sample means are significantly different.
