The titanic data records five variables for the passengers on
the ill-fated ship. Their age,
sex (male or female), from which port they
embarked (Cherbourg, Southampton or Queenstown),
their ticket class (first, second or third) and
whether they survived (yes/no).
Assuming the regression model below is valid, decide which of the
following is true.
age' = 93 - 8.1 sexMale - 9.3 survivedYes - 8.4 embarkedQueenstown
+ 82.6 embarkedSouthhampton
a.
The value of age would on average be 91 more for cases where the
level of embarked is Queenstown compared to when it is
Southhampton
b.
The level of age will be 8.1 when the level of sex is Female
c.
The level of age will be 9.3 when the level of survived is
No
d.
Cases where the level of embarked is Cherbourg tend to have a
higher amount of age compared to cases where the level of embarked
is Queenstown
