Title:
 On sample size in testing hypothesis about two means equality

Language: English

Keywords:
testing of hypothesis
sample size
Monte Carlo simulations

Summary:
The paper presents two methods of calculating the sample size to test hypothesis about two means equality with unknown and equal variances. Sample sizes for chosen differences in means d and standard deviations were calculated using the first method. The working of the second method was examined by means of the Monte Carlo simulations and the results were presented in histograms.
