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, 1926 users of the method gave birth to 945 males and 981 females. There is about a 21% chance of getting that many babies born female if the method had no effect. ..... Because there is a 21% chance of getting that many babies born female if the method had no effect, the method does not have practical significance. Not many 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 does not have practical significance.
