Which statement creates the TEST array that references the columns Test1, Test2, Test3, Test4, Test5, and Final?

The choice that creates the TEST array correctly is the first one, which specifies the elements to be included in the array by listing the variables explicitly. This syntax allows for a straightforward association of the array elements with the specified dataset variables.

In this context, 'array test[6] Test1-Test5 Final;' effectively defines an array named TEST with six elements. The notation 'Test1-Test5' indicates a range of contiguous variables from Test1 to Test5, while 'Final' is added as an additional, separate element of the array. This structure is not only valid syntax in SAS but also intuitive in its approach to array creation, making it clear which specific dataset columns are being referenced.

The other options may introduce ambiguity or incorrect syntax. For instance, the second option employs parentheses in a manner that does not conform to SAS array declaration rules. The third option suggests a use of the 'to' keyword incorrectly, which is not necessary when specifying a range with a combination of listing (as is done in the first option). The fourth option combines these elements with a comma, which does not correctly define the array according to SAS standards.

Thus, the syntax provided in the first choice is both clear and valid, making it the correct way to create
