What is true about the array Response declared in the SAS program?

In SAS, when you declare an array, the type of the array—either character or numeric—depends on how the elements of the array are defined. If you declare an array without specifically indicating that it is character or numeric, SAS defaults to creating a numeric array. Therefore, if the array "Response" is created without any character variables included in the declaration, it will be established as a numeric array of the specified size.

Typically, the declaration might look something like this:

array Response(5) _numeric_;

If the elements of the Response array are not explicitly defined as character variables, it confirms that the array comprises numeric variables.

Additionally, when creating arrays in SAS, separating elements with commas is not mandatory within the context of a declared array if the sizing is defined in parentheses. Furthermore, using an asterisk (*) within an array declaration often denotes an error if misapplied in context, but if the overall declaration follows the correct syntax structure for arrays, the presence of an asterisk would not inherently cause a syntax error.

Thus, the assertion that a numeric array of size 5 is created is consistent with how SAS interprets array declarations.
