Sample size calculations

Simulating an experiment

Picking n

The one sample problem. Is x-bar signficantly larger than a specified null value? Easier problem: Find n to work with a confidence interval. n = |Zalpha| sigma2 /(Interval width)2. Depending how you define width, you many need a factor of 2 in here also.

Picking all values

Need to pick all parameters.
