Answer:
A) 47
B) 65
C) 01
Step-by-step explanation:
A stem and Leaf is a unique way of representing data, in which every data value is split into a “stem” and “a leaf” . The “Stem” is the first Digit of the number and The “Leaf” is the second digit of the data value.
As we seen in the Key provided to us at the foot of the page, 6│3 represent 63,also
6│0 3 4 represents : 60,63,64
0│1 5 8 represents : 01,05,08
Using this rule we expands the data given to us and answer the questions given to us.
A) Number of people represented in data
0│1 1 2 2 3 4 4 4 4 5 8 = 01 01 02 02 03 04 04 04 04 05 08 = 11 Entries
In the same way , we count the other data and see that
Total number of data values are : 11+8+8+9+4+5+2= 47
B) The range of the Data: It the Difference of the largest Data value and the Lowest Data Value
Largest Data Value : 66
Smallest Data Value : 01
Range = 66-01 = 65
C) The mode : It the Data value which is repeated the most:
01 : 4 times
10 : 3 times
31 : 3 times
32 : 3 times
Hence the mode is 01
