For questions 54-60, refer to the following study and the accompanying SAS output:A study was conducted on 60 patients to examine the analgesic effects of treatments on elderly patients with neuralgia. Two test treatments and a placebo were compared. The response variable is whether the patient reported pain or not.LettersA, B, C, D, andEindicate missing numbers from the SAS output.Researchers recorded the following variables:

PAIN: patient reported pain (1=yes, 0=no)

TX: treatment (2=test treatment A, 1=test treatment B, 0=placebo)

AGE: age of the patient when the treatment began (in years)

SEX: sex (1=male, 0=female)

DURATION: duration of complaint before the treatment began (in months)

Testing Global Null Hypothesis: BETA=0
