Scenario: The data file called Sleeping Animals contains data about the size, sleep habits, lifespan, and other attributes of different mammalian species.

a. Construct box plots for Lifespan and Sleep. For each plot, explain what the landmarks on each plot tell you about the distribution of each variable.

Comment on noteworthy features of the plot.

b. Which distribution is more symmetric? Explain specifically how the graphs and descriptive statistics helped you come to a conclusion.

c. According to the data table, “Man” has a maximum life span of 100 years.

Approximately what percent of mammals in the data set live less than 100 years?

d. Sleep hours are divided into “dreaming” and “non-dreaming” sleep. How do the distributions of these types of sleep compare?

e. Select the species that tend to get the most total sleep. Comment on how those species compare to the other species in terms of their predation, exposure, and overall danger indexes.

f. Now use the Distribution platform to analyze the body weights of these mammals. What’s different about this distribution in comparison to the other continuous variables that you’ve analyzed thus far?

g. Select those mammals that sleep in the most exposed locations. How do their body weights tend to compare to the other mammals? What might explain this comparison?
