Mental Illness and Smoking

In the nicotine data, exclude all of the mental illnesses, so that the analyses will only include the "Control" and "Schizophrenia" subjects. Answer the following question:
What is the effect of mental illness and smoking history on the specific binding of nicotine receptors in the Thalamus?This is a two-way design. The response variable should be the Log Transformed Thalamus binding. Factors include Mental Illness (two groups) and Smoking Hx (3 groups). Write up the answer as though you are writing the results section in the paper (be concise but complete).

Notes: This is a straightforward ANOVA problem. All of your statistical decisions should be made based upon the transformed response variable. However, be careful to report initial summary means, etc. in terms of the original units.

Extra-credit: Back- transform estimated (predicted) means, CIs, and plots into original units. The confidence intervals will be symmetric about the mean in the log units but not symmetric in the original units. So how do you do a back-transformation? The transformation is A = Log(B), the reverse transformation is B = EXP(A). These formulas are available in JMP - make sure to use the LOG function, not the LOG10 function.

What is the effect of mental illness and smoking history on the specific binding of nicotine receptors in the Thalamus?
In the nicotine data, exclude all of the Mental Illness = Depressed (n = 9) subjects, so that the analyses will only include the "Control" and "Schizophrenia" subjects. Answer the following question:

What is the effect of mental illness and smoking history on the specific binding of nicotine receptors in the Thalamus?
Is there a difference in the mental illness and smoking history on the specific binding of nicotine receptors in the Thalamus?
Set up a null hypothesis:
HO : Mental illness mean = smoking history mean
The null hypothesis assume that the mean for the specific binding of nicotine receptor on mental illness patients would be the same as the mean of specific binding nicotine receptor on patients with smoking ...
