predicting gender of baby a study addressed the issue of whether pregnant women can correctly guess the gender of their baby. among 104 recruited subjects, 55% correctly guessed the gender of the baby (based on data from “are women carrying ‘basketballs’ really having boys? testing pregnancy folklore,” by perry, dipietro, and constigan, birth, vol. 26, no. 3). use these sample data to test the claim that the success rate of such guesses is no different from the 50% success rate expected with random chance guesses. use a 0.05 significance level

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?
