# Thread: IQR Again

1. ## IQR Again

Because I need the median???

The whole question was:

Costs for standard veterinary services at a local animal hospital follow a Normal Model with a mean of $80 and a standard deviation of$20.

Part A was to draw the model : which I did and got right
Part B was : Is it unusual to have a veterinary bill for $125? Explain : Which I did and got right....answer was Yes because only 1.2% of bills cost$125 or higher.
Part C was : What is the IQR for the costs of standard veterinary services? Show your work.

Thank you for helping me!!
