Refer to the accompanying data set and use the 25 home voltage measurements to construct a frequency distribution with five classes. Begin with a lower class limit of 122.0 ?volts, and use a class width of 0.2 volt.
Does the result appear to have a normal? distribution? Why or why? not?
Yes, because the frequencies start low, reach a maximum, then become low again, and are roughly symmetric about the maximum frequency.
