Because the sample mean (from data for current hours of sleep per night I collected) needs to be compared to a distribution of all possible sample means (i. e., the sampling distribution), calculate the standard error (standard deviation of the sampling distribution) from the estimated population variance that you just calculated in the previous question.

Points a, b, and c form a triangle. complete the statements to prove that the sum of the interior angles of triangle abc is 180

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.

In a young single person's monthly budget, $150 is spent on food, $175 is spent on housing, and $175 is spend on other items. suppose you drew a circle graph to represent this information, what percent of the graph represents housing?
