Need statistics help, possible not bell curve.

In one of my homework problems it asks to find the probability (area under curve) of some stuff, but it says the data is uniformly distributed, not normally distributed.
And since its only got nine samples, I cant assume its approximately normal either. No point in determining the Z-scores if its not a proper curve, though I could with the data given.
Already emailed the teacher but on a saturday I doubt I'll get a quick response.

Have any of you guys ever assumed a uniformly distributed curve is also a normal curve?

I think I may run the numbers anyway, intercept the teacher before class and if she says I cant assume that, erase it and put No Possible Solution.

The only reason this one is weird is I think she said there might be a problem I cant do and also because its sandwiched between two J-curves with a crapload of samples (way over 30).

Z-score does not depend on curve shape.

Sorry, not finding the z-score, finding the area under a z-score. The only way that works (in first semester Statistics) is if its bell shaped.

Well you know that the random variable is uniform (pdf looks like a rectangle). All you need to know is the range of the random variable and the probability or height of the rectangle (which is the same for the entire range). You can use the samples you're given to derive this and state that for the number of samples given, you believe the RV has these characteristics. Then, find the z-scores given the range.
