In preparation for the upcoming school year, a teacher looks at raw test scores on the statewide standardized test for the students in her class. Instead of looking at the scores relative to the norms in the state, the teacher wants to understand the scores relative to the students who will be in the class. To do so, she decides to convert the test scores into z-scores relative to the mean and standard deviation of the students in the class. The mean test score in her upcoming class is 49, and the standard deviation is 20.7.
The following are the scores for some (not all) of her students. Complete the table using the dropdown menus.
Student
Test Score
z-score
A 32 -0.82
B 45
C 66 0.82
D 55
E 33 -0.77
F 72
G 59 0.48
H 44
The teacher wants to identify those students who may need an extra challenge or extra help. As a first cut, she decides to look at students who have z-scores above z = 2.00 or below z = -2.00.
Identify the test score corresponding to each of the following z-scores. Round to the nearest whole number.
For z = 2.00, test score = .
For z = -2.00, test score = .

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.
