How to prove that a normally distributed assumption was fulfilled for the Two-Proportional z-test?
Select all relevant assumptions.
Residual graphs do not have a pattern
Scattered plots are linear
Scattered plots do not have a pattern
Normal sample distribution: npge5&n(1-p)ge5
Bell-shaped histograms
Histograms are uniform
Residual graphs are linear
Residual graphs are linear box plots have less than two outliers
Normal quantile plots do not have a pattern
Normal sample distribution: n,p,ge5,n,(1-p)ge5,n_2p_2ge5&91-p_2)ge5
Normal sample distribution: n'sge30 or populations usually are distributed

Two proportion z-test assumption is below:
Therefore the appropriate assumptions is:
Scatter plot are linear
Histograms are bell shaped
Normal quantile plots are linear
Residual plots are linear
Normal sampling distribution: all n≥30 or population are normally distributed.
