Part E of problem 2 asks if a histogram would be appropriate given the data. Consider what your data is ACTUALLY composed of: 200 zeroes, 85 ones, 45 twos, and so on. Remember that you are measuring the number of impairments, not the frequency. Frequency is simply the number of times that number shows up in the data.
Given that your data is composed of a bunch of zeroes, ones, and other small numbers, would it MAKE SENSE to use a stem and leaf plot here?
Problem Two part c asks to make a relative frequency histogram. Normally we can do this on the TI, but that trick only works if we have the raw data. We only have the frequencies. Use those to make your histogram. Don't forget to label and title!
