snow_lady [41]

y = -2x + 3

y = -x + 10

y = 4x + 10

y = 3/2x - 2

y = -1/2x - 1

y = x + 5

y = 25x + 5

y = .99x + 1.99

y = x - 2

y = -1.50 + 1.50

y = 42x + 27

y = -1/3x - 2

The dot plots below show the results.
shutvik [7]

Answer: The median for the students is 2 and the median for the teachers is 3.

Step-by-step explanation:

Ordering the data for the students from the dot points:

0, 0, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4.

n = 20 which is positive so median position is average of:

= (n / 2)                                     and                                = (n + 1) / 2

= 20 / 2                                                                           = 21 / 2

= 10                                                                                 = 10.5

2 is in position 10                                                         2 is in position 10.5

Average = (2 + 2) / 2 = 2

Student median is 2.

Teachers

0, 1, 1, 1, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 6, 8

3 is in position 10 as well as in position 10.5.

= (3 + 3) / 2

= 3

Teacher median is 3.
