The objective function for an optimization problem is: Max 5x  3y, with constraints x  0, y  0 and y must be an integer. x and y are the only decisions variables. This is an example of a(n)
 a. all-integer linear program.
  b. mixed-integer linear program.
  c. LP relaxation of the integer linear program.
  d. binary integer linear program.

Question 2

A Type I error is committed when
 a. a true alternative hypothesis is not accepted.
 
  b. a true null hypothesis is rejected.
  c. the critical value is greater than the value of the test statistic.
  d. the validity of a claim was rejected.

Answer to Question 1

b
RATIONALE: If some, but not necessarily all, variables are required to be integer in a linear program, then it is a mixed-integer linear program.

Answer to Question 2

b
RATIONALE: If we reject H0 when H0 is true, we have made a type I error. Said another way, a type I error is committed when a true null hypothesis is rejected.
