Ten children measured how high they could jump. The results they recorded, in inches, were as follows: 8, 9, 8, 6, 8, 12, 9, 10, 11, 16 What is the median of these measures? A. 8 in.
B. 9 in.
C. 9.5 in.
D. 10 in.
E. None correct

b) 9 in

Step-by-step explanation:

To find median arrange the data in ascending order and count the number of data's. if the total number of data is odd number, then (n/2)th term is the median.

If the total number of data is even, then Average of (n/2)th term and (n/2)+1 th term is the median

Ascending order:

6, 8, 8 , 8 , 9 , 9 , 10 , 11 , 12 , 16

total = 10. so even number

Median = average of 5th term and 6th term

             =(9+9)/2

             = 18/2

              = 9

step-by-step explanation:

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.
