A simple random sample of 40 college students was surveyed. The number of participants in given age ranges were recorded in the table below. Complete the table, computing the class midpoints, relative frequencies, cumulative frequencies and the cumulative relative frequencies for each class. Express answers as decimals rounded to 2 decimal places. Then use the table to answer the following questions. Ages Class Midpoint Frequency Rel. Freq. Cumulative Freq. Cumulative Rel.

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?...
