You use a z test when you are testing a hypothesis that is using proportions You use a t test when you are testing a hypothesis that is using means

The"t" test, (called the "small 't' test, to distinguish it from the large 'T' test) is a test for deviation from a known norm, using a smaller sample set than the one required by the large T test. It is said to have been developed by the head of quality control at the Guinness Brewery in Ireland.

t test, because the z test requires knowing the population standard deviation and that's rare. The t test embodies an estimate of the standard deviation.

yes

Convenient sampling refers to using a sample group that is the easiest to gather. The advantage of this is that it is the easiest way to convene a test group. The down side is that the sample may not be representative of the population, so the results will be skewed.

You can test data using T-Test in SPSS. Click Analyze > Compare Means > Independent-Samples T-Test to run an Independent Samples T-Test in SPSS. In the Independent-Samples T-Test window, you specify the variables to be analyzed. On the left side of the screen, you will see a list of all variables in your dataset.

If we are testing a hypothesis about the population mean , if none of the conditions of using a z-score or the conditions for using a t-score are met, we may use a proper non-parametric test.
