Abstract

It is of interest to make an inference about the mean expenditure per tourist per day (or per stay). A simple approach to obtain an exact t test under stratified random sampling is proposed in this study. The underlying assumptions include given prior probabilities, normality within each stratum, and the equality of within-stratum variances. Procedure to make an exact inference has been provided and illustrated. The proposed approach is effective and recommended for the studies where stratified random sampling is conducted and inference for the mean expenditure is desirable.
