Concentrating on lone companies with known position of independency. trial whether Indic.
the population proportion of companies with no recorded stockholder with more than 25 % direct or entire ownership ( A ) is the same for each brace of states.
Hint: Do non include companies with unknown position of independency in this trial. Re-code this variable in the filtered sample into:
