1. Hospital length of stay and insurance type (Medicare, Medicaid, private, self-pay). NB: in this problem, there are four types (categories) of insurance.
Hint: the dependent variable is given first.
Select one:
a. Logistic regression (Logit)
b. t-test
c. Analysis of variance (ANOVA)
d. Regression
e. Chi-square
2.Cost per hospital stay in relation to the following patient characteristics: sex, age and whether medical or surgical admission.
Hint: the dependent variable is given first.
Select one:
a. Logistic regression (Logit)
b. t-test
c. Analysis of variance (ANOVA)
d. Chi-square
e. Regression
3.Whether a woman desires an additional child and the number of children she has who are now living categorized as none, one or two, and three or more.
Hint: the dependent variable is given first.
Select one:

c. Regression
d. t-test
e. Logistic regression (Logit)
4. Blood pressure readings for a group of people before and after the initiation of a six-week program of exercise and diet.
Hints:
The independent variable here is time (before, after the exercise and diet program).
The dependent variable is given first.
Select one:
a. Logistic regression (Logit)
b. Analysis of variance (ANOVA)
c. t-test
d. Chi-square
e. Regression
5. Birth weight for newborns measured as low or normal in relation to the newborn’s gestational age, mother’s age and mother’s smoking status (smoker, non-smoker).
Hints:
The independent variable here is time (before, after the exercise and diet program).
The dependent variable is given first.
Select one:
a. Chi-square
b. Logistic regression (Logit)
c. t-test
d. Regression
