1) Does taking an aspirin a day help reduce migraine frequency? In a study of 180 volunteers of patients who have cases of daily migraines, half were randomly assigned to take an aspirin every morning and the other half was given a pill that looked identical to the aspirin but had no active ingredients. The patients were told to keep a record of the number of migraines they had each day for the next three months. a. Comment briefly on the extent to which the results of this study can be generalized to some larger population, and the extent to which cause and effect has been established. b. It is well known females have more migraines than males. If this is the case, what type of experimental design would you choose for this study, and why?

It is well known females have more migraines than males. If this is the case, what type of experimental design would you choose for this study, and why? c. Assume there were 100 females and 80 males for this experiment. Describe a design for this experiment. Be sure to include a description of how you assign individuals to the treatment groups. d. The researchers of this experiment stated there was statistically significant evidence taking an aspirin a day lowered the frequency of migraines. What does "statistically significant evidence" mean in the context of this study?
