A corporation maintains a large fleet of company cars for Its sales people. To check the average number of miles driven per month per car this year, a random sample of 40 cars is examined. The mean and standard deviation for the samples are 2752 mi/mo., and 350 mi/mo., respectively. It is known that the average number of miles driven per car per month was 2600 and sigma = 350 from the previous records. Test the claim that the mean mileage driven per car per month is different from that of the previous records. Let alpha = 0.05. a. State the requirements. Does it meet the appropriate requirements? b. State H_0 and H_a. c. Compute the test statistic. d. Find the critical value and p value. State your conclusion and interpret.

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.
