Determine whether the results appear to have statistical significance, and also determine whether the results appear tohave 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 themethod gave birth to 945 males and 981 females. There is about a 21% chance of getting that many babies bornfemale 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 methoddoes not have practical significance.Not many couples would likely use a procedure that raises the likelihood of ababy 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.

We see, In a sample of 1926 users, observed that the method gave birth to 945 boys and 981 girls.…
