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). Be sure to embed your histogram in the textbox along with your response - and include theAlt Text (directions). Please do not submit your histogram as an attachment.
2. The second histogram for the distribution of ages, and adjust the bin width (directions). Try both smaller and larger bin widths. Choose a bin width so that your second histogram does not look like the first. Also embed your second histogram in the textbox with your response. Indicate which histogram is better for analyzing the data (your first embedded histogram or your 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?
