z-critical value: Based on your z-statistic and z-critical values, what can you conclude abot the researchers' claim that survey respondents, on average, are older than the general Bangladesh population for this survey region? The correct decision is to the null hypothesis that the average age of a survey respondent is equal to 29.8 years because there is evidence at the a = 0.01 level against this claim. Adapted from Raihan M. et al. Examining the relationship between socio-economic status, WASH...
