Answer 1

Solution:-
Because there is a 15% chance of getting that many girls by chance, the method does not have statistical significance

By this method , Percentage of girls = 1032/2016 = 0.5119

=> Not many couples would likely use a procedure that raises the likelihood of a girl from the approximately 50% rate expected by chance to the 51.19% produced by this method, so this method does not have practical significance.
