Question #16

The data set CM has eight variables including CMTRT and is sorted by STUDYID USUBJID CMSEQ.

DATA_BB is created by selecting records from CM where the character string "BLOCKER" is included in CMTRT.

Which program was used to produce WORK.DATA_BB?

  • A . proc sort data=cm out=data_bb (keep=usubjid cmstdtc cmtrt);
    by usubjid CMSTDTC;
    where cmtrt in(‘BLOCKER’);
    run;
  • B . proc sort data=CM (keep=usubjid cmstdtc cmtrt) out=data_bb;
    by usubjid CMSTDTC;
    where cmtrt contains ‘BLOCKER’;
    run;
  • C . data data_bb;
    set cm (where=(find(cmtrt,’BLOCKER’,’i’)>0));
    by usubjid CMSTDTC;
    run;
  • D . data data_bb;
    set cm (keep=usubjid cmstdtc cmtrt);

Question #18

The first six (6) records from the LABS data set are shown below:

The following SAS program is written to reshape this data set and place it in a new data set named LBTR.

proc transpose data=labs out=lbtr(rename = (col1 = value));

by subjid sampldat;

var Calcium Glucose Hemoglobin;

run;

Which of the following DATA steps produces a data set that is equivalent to the LBTR data set created by the PROC TRANSPOSE step above?

  • A . data lbtr2(drop = i calcium glucose hemoglobin);
    set labs;
    array orig[3] calcium glucose hemoglobin;
    array testcds[3] $ 10 _temporary_ ("CALCIUM" "GLUCOSE" "HEMOGLOBIN");
    do i = 1 to 3;
    value = orig[i];
    _name_ = testcds[i];
    output;
    end;
    run;
  • B . data lbtr2(drop = i calcium glucose hemoglobin);
    set labs;
    array orig[3] calcium glucose hemoglobin;
    array testcds[3] $ 10 _temporary_ ("CALCIUM" "GLUCOSE" "HEMOGLOBIN");
    do i = 1 to 3;
    value = orig[i];
    _name_ = testcds[i];
    end;
    output;
    run;
  • C . data lbtr2(drop = i calcium glucose hemoglobin);
    set labs;
    array orig[3] calcium glucose hemoglobin;
    array testcds[3] $ 10 ("CALCIUM" "GLUCOSE" "HEMOGLOBIN");
    do i = 1 to 3;
    value = orig[i];
    _name_ = testcds[i];
    end;

Question #20

The print below shows the first four observations from the TEST2 dataset.

Variable names are given in the first row.

The statistical analysis plan (SAP) requests that a two sample t-test be performed to compare the mean of variable FINALBP for levels of the variable TRT.

You review the following code from a colleague:

proc ttest data=test2;

by trt;

var finalbp;

run;

This code does not produce the analysis requested by the SAP.

What is wrong with this code?

  • A . Variable FINALBP should be specified on a TWOSAMP statement instead of a VAR statement.
  • B . Variable TRT should be specified on a CLASS statement instead of a BY statement.
  • C . Variable FINALBP should be specified on a TEST statement instead of a VAR statement.
  • D . Variable TRT should be specified on a WEIGHT statement instead of a BY statement.
