Z-Test Execution

[heber_brandao]

Hello everybody,

Currently we have been trying to execute the z_test(data, value, stdev) function based on a bunch of data between test/control groups.

What the documentation is lacking is a bit of description on how does each of this input need to be given:

• data - what data does it refer to?
• value - the hypothesized mean
• stdev - the standart deviation

For the last 2 inputs, I already have data. But which input should I give on data?
