The data represents the daily rainfall (in inches) for one month. Construct a frequency distribution beginning with a lower class limit of 0.00 and use a class width 0.32 of 0.20.

O A. No, although the frequencies start low, increase to some maximum, then decrease, the distribution is not symmetric. O B. No, the distribution is not symmetric and the frequencies do not start off low. O C. Yes, all of the requirements are met. O D. No, although the distribution is approximately symmetric, the frequencies do not start low, increase to some maximum frequency, then decrease.
