1. Suppose you need to create a variable, MaxValue, that is equal to Units times the maximum of PriceApril, PriceMay, and PriceJune. Which assignment statement will do this?

   	a.	maxvalue=units**sum(PriceApr,PriceMay,PriceJun);
   	b.	MaxValue=units*max(PriceApr,PriceMay,PriceJun);
   	c.	maxvalue=units**mean(PriceApr,PriceMay,PriceJun);
   	d.	MaxValue=units*scan(PriceApr,PriceMay,PriceJun);

2. The assignment statement is one of the few SAS statements that does not:

   	a.	begin with a keyword
   	b.	end with a semicolon
   	c.	support mixed-case variable names
   	d.	allow the use of comparison operators

3. Consider the small data set and program shown below. What is the value of Count after the fourth observation is read?

   SAS Data Set Work.Numbers Tens 10 20 30 40 50

   data work.newnums; set work.numbers; Count+tens; run;

   	a.	missing
   	b.	0
   	c.	50
   	d.	100

4. For the observation shown below, what is the result of the IF-THEN statement?

   Status	Type	Count	Condition	Control
   ok	3	12	E	Go

   if status='OK' and type=3
      then count+1;
   if status='S' or condition='E'
      then control='Stop';

   	a.	Count = 12    Control = Stop
   	b.	Count = 12    Control = Go
   	c.	Count = 13    Control = Stop
   	d.	Count = 13    Control = Go

5. Consider the IF-THEN statement shown below. When the statement is run, which expression is evaluated first?

   if mean(MidTerm,FinalExam)>=95
      and (ResearchPaper='A' or
          (Project='A' and Presentation='A'))
      then grade='A+';

   	a.	mean(MidTerm,FinExam)>=95
   	b.	ResearchPaper='A'
   	c.	Project='A' and Presentation='A'
   	d.	ResearchPaper='A' or (Project='A' and Presentation='A')

6. Which set of statements is equivalent to the code shown below?

   if code='1' then Type='Fixed';
   if code='2' then Type='Variable';
   if code^='1' and code^='2' then Type='Unknown';

   	a.	if code='1' then Type='Fixed'; else if code='2' then Type='Variable'; else Type='Unknown';
   	b.	if code='1' then Type='Fixed'; if code='2' then Type='Variable'; else Type='Unknown';
   	c.	if code='1' then Type='Fixed'; else code='2' and Type='Variable'; else Type='Unknown';
   	d.	if code='1' and Type='Fixed'; then code='2' and Type='Variable'; else Type='Unknown';

7. Which of the following does not determine the length of a new variable?

   	a.	the variable's first reference in the DATA step
   	b.	the length of the variable's first value
   	c.	the assignment statement
   	d.	the LENGTH statement

8. What is the length of the variable Type, as created in the DATA step below?

   data finance.newloan;
      set finance.records;
      TotLoan+payment;
      if code='1' then Type='Fixed';
      else Type='Variable';
      length Type $ 10;
   run;

   	a.	5
   	b.	8
   	c.	10
   	d.	it depends on the first value of Type

9. Which set of statements is equivalent to the code shown below?

   length Type $ 14;
   if code='1' and months=360 then
      type='Fixed Mortgage';
   else if code='1'
        then type='Fixed Other';
   else type='Variable';

   	a.	length Type $ 14; if code='1' then if months=360 then type='Fixed Mortgage'; else type='Fixed Other'; else type='Variable';
   	b.	length Type $ 14; if code='1' then do if months=360; type='Fixed Mortgage'; else type='Fixed Other'; end; else type='Variable';
   	c.	length Type $ 14; if code='1' then do; if months=360 then type='Fixed Mortgage'; else type='Fixed Other'; end; else type='Variable';
   	d.	length Type $ 14; if code='1' then do; if months=360 then do; type='Fixed Mortgage'; end; type='Fixed Other'; end; else type='Variable';

10. Which version of the code will run correctly?

    	a.	if code='1' then do; if months=360 then do; Type='Fixed Mortgage'; note='Check current prime rate.'; else Type='Fixed Other'; else Type='Variable';
    	b.	if code='1' then do; if months=360 then do; Type='Fixed Mortgage'; note='Check current prime rate.'; end; else Type='Fixed Other'; end; else Type='Variable';
    	c.	if code='1' then do; if months=360 then Type='Fixed Mortgage'; note='Check current prime rate.'; end; else Type='Fixed Other'; else Type='Variable';
    	d.	if code='1' then if months=360 then do; Type='Fixed Mortgage'; note='Check current prime rate.'; else Type='Fixed Other'; end; else Type='Variable';
