The AP Statistics class at the Hallways School for Girls takes a random sample of 50 students (from the school population of 698) and asks them if they get enough sleep. 18 of the respondents say "yes."
a. Check that all conditions for using the normal approximation to the sampling distribution are met in this scenario.
b. Construct a 95% confidence interval for the proportion of students at the Hallways School for Girls that will say they get enough sleep
c. Before doing this poll, Anna hypothesized that only 25% of all Hallways girls will say they get enough sleep. Based on your data and answer from
part (a) do you think Anna's hypothesis should be rejected? Should it be accepted?
d. If 42% of all girls at Hallways School for Girls would actually say they get enough sleep, what is the probability of getting a sample with as few (or
fewer) "yes" answers as the AP class got?

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.
