1. Describe the distribution of IAT participants' ages in your sample. Your description should include: shape, center, spread, a typical interval of representative ages, and any apparent outliers (unusual ages).
2. The second histogram is the distribution of ages, and adjusted bin width. Indicate which histogram is better for analyzing the data ( the first embedded histogram or the second). Explain why.
3. Your random sample was obtained from the population of participants for your chosen IAT data set. Based on the histogram from your random sample, how would you describe the population of participants for your chosen IAT data set? Do you think the IAT population is similar to the U.S. population?
