According to the Centers for Disease Control and Prevention (CDC) Web site, 60% of high school students have never smoked a cigarette. James wonders whether the percentage in his large, urban high school is higher than the national result.

Carry out a significant test at the a=0.05 significant level. USE PHANTOMS

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
