Formula Question: Limit Variable Values to Specific Quantities

I'm trying to write formula questions for my engineering class, and I'm working with fairly large input values. For example, one input variable in my current quiz over stress-strain calculations is 65,000 psi.

 

I want the quiz to involve formulas so that the psi changes for each student, but I don't want it to vary down to the ones digit (for purposes of significant figures, etc.). In other words, I don't want 64,303 psi to show up in a problem. 

 

Can I set up a list of potential input variables and then have the formula randomly choose one of these to use? 

 

Example:

Options for input for psi: 50,000 / 55,000 / 60,000 / 65,000 / 70,000

 

Set up a formula to choose one of those 5 specific values.

 

I've done this in ExamView for years, but I don't know how to do it within Canvas. Thanks in advance!
