Questions on using t-test

Is it possible to use t-test to check significant difference of large sample? We have around 2800 service users and 72% of them are male. We would like to test the significant difference of the gender. Thanks!

will the results be biased if the difference in the number of male and female participants is large?

The t-test is generally versatile and robust. It is certainly useful when the sample is large.

Local NGOs have reported that younger workers are more susceptible to layoffs than their older and more experienced colleagues. Could this claim potentially trigger policy changes?

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?
