Question

Determine whether the results appear to have statistical significance, and also determine whether the results appear to have practical significance.

In a study of a birth sex selection method used to increase the likelihood of a baby being born female, 1929 users of the method gave birth to 945 males and 984 females. There is about a 19% chance of getting that many babies born female if the method had no effect. Because there is a 19% chance of getting that many babies born female if the method had no effect, the method (has practical significance.has statistical significance.does not have practical significance.does not have statistical significance.)Not many Most couples would likely use a procedure that raises the likelihood of a baby born female from the approximately 50% rate expected by chance to the

% produced by this method.

(Round to the nearest integer as needed.)

So, this method (has statistical significance. has practical significance.

should be used to make conclusions. does not have practical significance.)
