SMPLSIZE

This program will determine the sample size required for the following scenarios:

1) 1-Sample Normally distributed using the margin of error formula (one taught in most first semester statistics courses)
2) 1-Sample Normally distributted using Type I and Type II Errors (Lehr's Formula)
3) 1-Sample Normally distributed Proportion using margin of error formula (one taught in most first semester statistics courses)
4) 2-Sample Normally distributed using Type I and Type II Errors
5) 2-Sample Normally distributed Proportions using margin of error formula (this formula assumes that the sample sizes will be the same for both samples, see Michael Sullivan's text: Statistics, Informed Decisions Using Data).
6) 2-Sample Normally distributed Proportions using Type I and Type II error formula ( Casagrande, Pike and Smith's formula that uses a continuity correction).

Enjoy!
