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 gender selection method used to increase the likelihood of a baby being born a girl, 2097 users of the method gave birth to 1031 boys and 1066 girls. there is about a 23% chance of getting that many girls if the method had no effect.

Answer and Explanation:

Because there is a 23% chance of getting that many girls by?chance, the method has A) has statistical significance B) does not have statistical significance C) has practical significance D) does not have practical significance. A) Most or B) Not many couples would likely use a procedure that raises the likelihood of a girl from approximately? 50% rate expected by chance to the what % produced by this method, so this method A) has statistical significance B) does not have practical significance C) does not have statistical significance. D) has practical significance.

Since there is a 23 percent probability which many women can get by probability, Method B) has no statistical significance

From this method, the girl's percentage is

= 1066 ÷ 2097

= 0.5084

or

= 50.84%

Not so much of couples will actually use a technique that increases a girl's probability from the approximately 50 percent rate predicted by chance to the 50.84 percent provided by this process, so this approach B) has no practical significance
