Thirty-nine students (26 women and 13 men) reported their ideal weight (in most cases, not their current weight). The tables show the data.
a. Explain why the distribution of ideal weights is likely to be bimodal if men and women are both included in the sample.
b. Make a histogram combining the ideal weights of men and women. Use the default histogram provided by your software. Report the bin width and describe the distribution.
c. Vary the number of bins, and print out a second histogram. Report the bin width and describe this histogram. Compare the two histograms.
