(a)
To construct: the stem and leaf plot on basis of given data.
(a)
Explanation of Solution
Given:
228, 178, 186, 162, 206, 166, 163, 183, 181, 206, 177, 175, 167, 162, 160, 160, 157, 156, 153, 153, 152
Graph:
Stem unit = 10
Leaf unit = 1
By seeing the distribution, it is observed that the distribution is not symmetric distribution the reason is that the distribution is skewed to right and has outliers so
(b)
To Explain: the distribution and overall shape and unusual features.
(b)
Answer to Problem 36E
Right skewed
Explanation of Solution
Given:
228, 178, 186, 162, 206, 166, 163, 183, 181, 206, 177, 175, 167, 162, 160, 160, 157, 156, 153, 153, 152
Graph:
Stem unit = 10
Leaf unit = 1
By seeing the distribution, it is observed that the distribution is skewed to the right although the most of the data points are on the. All but three numbers are over 200 and the number 228 might be an outlier. There are total 21 numbers of the data list so the median is 11th position. So the median is 166 birds.
