문제1

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 TEST statement instead of a VAR statement.

B. Variable TRT should be specified on a WEIGHT statement instead of a BY statement.

C. Variable FINALBP should be specified on a TWOSAMP statement instead of a VAR statement.

D. Variable TRT should be specified on a CLASS statement instead of a BY statement.

정답: D
