# importing numpy

I'm in the mathlab and trying to import numpy with python, and its giving me this error:

Traceback (most recent call last):

File "", line 1, in

ImportError: No module named numpy

it seems very difficult to complete the last problem on 09: confidence interval homework without using this software...

## Comments

Yes, it's hard to do this type of problem without using software. That's rather the point! We are learning how to do statistics and, in practice, statistics often uses software.

As far as you're specific question goes, it's hard to say for sure without more complete information but it sounds like you're using the Microsoft system Python, rather than Anaconda. Be sure that you're firing up Anaconda on that machine, as we did in class.

Even lacking that, there's plenty of software that will compute mean and standard deviation of a list of numbers, which is all you really need. You could use a spreadsheet or Mathematica, for example. There's also a Python interpreter built into the online Sage Cell Server. You can use that like so.
