For each variable of interest – Percent Time Asleep and Longevity – create a grouped frequency histogram. For each histogram, use a class width of 10; use a lower limit of 0 for Percent Time Asleep and 15 for Longevity. Each histogram must include an informative title, along with correct labels for both axes. For each histogram, include a paragraph that answers each of the following questions: Is the histogram symmetric, skewed to the left, or skewed to the right?...
