Answer:
Stem Leaf
______________
0 | 4 8
1 | 0 5
2 | 5
3 | 3 6 6
4 | 0 0 9
5 | 0
6 | 3 4 6
______________
Notation : 0|4 means 04 or 4 , 4|9 means 49/
For this case we can conclude that the distribution is approximately symmetrical.
For the 5 number summary we have
Minimum = 4 , Q1= 20 , Median =36, Q3= 49.5 , Maximum = 66
The mean for this case is Mean= 35.93
And as we can see since the mean is similar to the the median
The mode is 40 and 36 (bimodal distribution) with frequency of 2
Step-by-step explanation:
Data given:
4 15 10 8 33 25 36 40 36 66 63 50 64 49 40
For this case the first step is order the dataset on increasing way and we got:
4 8 10 15 25 33 36 36 40 40 49 50 63 64 66
Now we can construct the stem leaf plot like this:
Stem Leaf
______________
0 | 4 8
1 | 0 5
2 | 5
3 | 3 6 6
4 | 0 0 9
5 | 0
6 | 3 4 6
