Question 3
Researchers are studying which variables impacted survival of crew and passengers aboard
the Titanic during its historic sinking. They fit a model of the form:
log (Por) = bo + b₁ Class2nd + b₂Class3rd + b3 ClassCrew + b₁ SerFemale +bş Age Adult
Researchers estimate a value of 64 -0.503. Based on this, what is the increase in the odds of
survival for a female passenger compared to a male passenger?
Your answer should be a percentage rounded to 2 decimal places. (IE: .12345 becomes 12.35)
(Hint: an odds ratio of 1.10 would indicate a 110% relative odds, and a 10% increase)
Question 4
Researchers are studying which variables impacted survival of crew and passengers aboard
the Titanic during its historic sinking. They fit a model of the form:
log(
(Peru) = bo + b₁ Class2nd + b₂ Class3rd + b3 ClassCrew + b4 Sex Female + b5 Age Adult
Researchers estimate a value of 12 =-0.308. Based on this, what is the decrease in the odds
of survival for a 3rd class passenger compared to a 1st class passenger?
Your answer should be a percentage rounded to 2 decimal places. (IE: .12345 becomes 12.35)
(Hint: an odds ratio of .90 would indicate a 90% relative odds, and a 10% decrease; your
answer should be a positive value)
