## Re: Iqr?? Ugh!!!

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!!

Well now that we know that it's normally distributed, convert to the standard normal probability density function. Then you need to work out where the middle 50% of the data lie. So evaluate where 75% of the data lie beneath for Q3, where 25% of the data lie beneath for Q1, then you will be able to evaluate the IQR.
