For questions 58-60, 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)

58.How many dummy variables need to be included in the model for TX?

a.3

b.2

c.1

d.0

e.Cannot be determined from the given information

59.What is the estimated odds ratio for reporting pain for a 65-year-old compared to a 60-year-old, controlling for all other variables in the model?

a.0.26

b.1.30

c.1.69

d.3.71

e.7.30

60.Given the estimated odds of reporting pain for a 65-year-old male in treatment group A with a complaint duration of 14 days is 0.165, what is the corresponding risk of reporting pain?

a.0.03

b.0.14

c.0.17

d.1.18
