- What percentage of signers were under 50 years of age?
- Next, sketch a relative frequency histogram of the age of the signers.
- Comment on the shape of the histogram (i.e. is it normally distributed, right-skewed, left-skewed)?
- Construct a stem-and-leaf plot for the age of the signers, using the first digit as the stem and the second digit as the leaf:
- Construct a dot plot of the age of the signers:
