Answer:

Part A) Median = 44

Part B) Median = 36

Step-by-step explanation:

Median of a data set is the middle data point.

Part A) Median of the data in this stem-and-leaf plot.

The total data set represented by Stem and leaf in order from least to greatest are as following:

37 , 38 , 38 , 40 , 43 , 45 , 47 , 47 , 51 , 52

The middle data is 43 , 45

So, median = (43 + 45)/2 = 88/2 = 44

Part B) Median of the data in A number line.

The total data set represented by the number line in order from least to greatest are as following:

31, 34 , 34 , 35 , 37 , 38 , 38 , 39

The middle data is 35 , 37

So, median = (35 + 37)/2 = 72/2 = 36
