Will give brainliestthe box plots below show student grades on the most recent exam compared to overall grades in the class: which of the following best describes the information about the medians? the exam median is only 1–2 points higher than the class median. the exam median is much higher than the class median. the additional scores in the second quartile for the exam data make the median higher. the narrower range for the exam data causes the median to be higher.

The exam median is much higher than the class median.

Step-by-step explanation:

The median is represented by the line in the box. The median is a common measure of the center of the data. Half of the observations are less than or equal to the value, and the other half is greater than or equal to the value.

You can see in the graph that the class median is almost in the middle, while the median of the exam is quite shifted to the right of the box. Hence, the answer is:  

The exam median is much higher than the class median.

Hope this helps!

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

understand that i don't know the answers

will someone answer his question
