Are calc-based stats classes useful for decision making?

[annoyinggirl]

If business degrees require only intro to stats class that contains no calculus, and stats could be summarized into a short, easy, one semester course, are taking calculus-based statistics courses after intro to stats helpful for decision making, or are the calc-based stats courses merely just use calculus to prove the material in intro to statistics course?

Yes... specifics of calc based stats courses varies between schools but the calc is not just about proofs.
All knowledge helps with decision making, particularly stats tools. Getting good with advanced tools is helpful.
