12. The math department at a small school has 5 teachers. The ages of these teachers are 23, 34, 37, 42, and 58.Suppose you selected a random sample of 3 teachers and calculated the sample median.(a) List all 10 possible samples of size 3. Calculate the sample median for each sample.

Step-by-step explanation:

From the question we are told that

5 samples(23 34 37 42 58)

To select 3 random sample

a) Generally to find all 10 possible outcomes and there median we make a table

Therefore

L1

58,42,37  Median=42

L2

58,42,34  Median=42

L3

58,42,23  Median=42

L4

37,34,23  Median=34

L5

58,37,34  Median=37

L6

58,37,23  Median=37

L7

58,34,23  Median=34

L8

42,37,34  Median=37

L9

42,37,23  Median=37

L10

42,34,23  Median=34

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
