Concept explainers
To find: the shape, center and spread of the distribution and mention if there is any outlier.
Answer to Problem 39E
80 and 90 appear to be outliers, Shape: right-skewed,Center: 15,Spread: 15,
Explanation of Solution
Given:
Calculation:
Shape: right-skewed, because most of the data points lie to the left and thetail lies to the right.
Center: 15, because most of the dots appear above 15 in the dot-plot.
Spread: 15, because there is a distance of about 15 from the mean to the shortest endpoint of the graph (0).
Outliers; There are outliers present, because there are large gaps in the dot-plot. More precisely, 80 and 90 appear to be outliers, because these two dots are far apart from the rest of the dots.
Conclusion:
Therefore,80 and 90 appear to be outliers, Shape: right-skewed,Center: 15,Spread: 15,
