Explanation of Solution
Given:
155, 142, 125, 150, 68, 95, 97, 75, 103, 125, 115, 133, 105, 85, 110, 120, 130, 129, 138, 135, 88, 109, 65, 80, 80, 71, 68, 90, 115, 115, 90, 70, 65, 69, 78, 97, 110, 71
Graph:
Stem unit = 10
Leaf unit = 1
On the basis of given data, plot the stem and leaf plot, it is observed that the distribution in not symmetric. It is right skewed or positively skewed. It is bi-modal and not having any outliers.
