Question 1.

Medical researchers are interested in the relationship between alcohol use along with other life-style characteristics and the development of diseases, such as cancer and hypertension. The hypothetical data in Table 7-17 could result from an ANOVA in a study comparing the mean blood pressures of patients who consume different amounts of alcohol. What is the total variation?

The subjects were instructed to take the formulation during their next migraine episode and rate their pain response on a scale of 'I'IO {10: most pain} How many levels has this study?
