Answer:
For part A: Range is difference between the highest value and lowest value of the data set.
For part B: Range is 5.2
Step-by-step explanation:
For part A:
Range of a data set is difference between the highest value and lowest value of the data set.
For part B:
From stem and leaf and it's key ,we can write our data set as
12.3,12.3,12.612.7,12.9,12.9,13.1,13.1,13.4,13.5,13.5,14.0,14.0,14.2,14.3,14.3,14.8,14.8,14.9,15.2,15.2,15.2,15.2,15.2,15.3,15.5,15.5,15.7,16.4,16.5,16.5,16.9, 16.9, 17.3,17.5.
Lowest value of data set = 12.3
Highest value of the data set =17.5
So, range = highest value- lowest value= 17.5-12.3 =5.2
