a) ?
b) .
c) -
d) !

Answer 1

In a SAS program, the sign that holds only the missing numeric values is option b) . (a period).

Step-by-step explanation:

In a SAS program, the sign that holds only the missing numeric values is option b) . (a period).

In SAS, a period (.) is used as the missing value indicator for numeric variables.

For example, if a variable called 'age' is missing for a particular observation, it would be represented as 'age = .'. This allows SAS to distinguish between actual values and missing values when performing calculations or data manipulations.
