Options: (probably)

a. a disturbance that travels through a medium with a transfer of energy and matter

b. a disturbance that travels through a medium without a transfer of energy and matter

c. a disturbance that travels through a medium with a transfer of energy and without a transfer of matter

d. a disturbance that travels through a medium with a transfer of matter and without a transfer of energy

e. a disturbance that travels only in the absence of matter

Answer:

c. a disturbance that travels through a medium with a transfer of energy and without a transfer of matter 

Waves involve the transport of energy without the transport of matter. In conclusion, a wave can be described as a disturbance that travels through a medium, transporting energy from one location (its source) to another location without transporting matter.

In physics, mathematics, and related fields, a wave is a propagating dynamic disturbance (change from equilibrium) of one or more quantities, sometimes as described by a wave equation. In physical waves, at least two field quantities in the wave medium are involved. Waves can be periodic, in which case those quantities oscillate repeatedly about an equilibrium (resting) value at some frequency.

Answers:

1.) C - Final exams: midterm = Q3 92 - Q1 80 = 12 and finals = Q3 85 - Q1 78 = 7, so finals exam has the smaller IQR.

2.) B - exam median is much higher than the class median: refer to the attached image of class and exam box and whisker graph

3.) A - IQR is a better measure of spread for movies than it is for basketball games: because the data for movies are quite wide or apart from each other than the data in the basketball games

4.) A - mean for April is higher than October's mean: mean in April is 67 and mean in October is 60

5.) A - Neither data set has suspected outliers: meaning there's no data that is further apart from the group or set

6.) B - There is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical 

7.) C - college spread is best described by the IQR. The high school spread is best described by the standard deviation: this is because of the wide range of data in the college than the data in the high school.
