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 123.5 volts, and use a class width of 0.2 volt. Does the result appear to have a normal distribution? Why or why not? E Click the icon to view the data. Complete the frequency distribution below. Frequency Voltage (volts) 123.5 - 123.6 5 123.7 - 123.8 123.9 - 124.0 4 124.1 - 124.2 6 124.3 - 124.4 (Type integers or decimals rounded to the nearest tenth as needed.) Does the result appear to have normal distribution? Why or why not? O A. No, because the frequencies are not equal across the voltage classes. O B. No, because the frequencies are roughly equal across the voltage classes. OC. Yes, because the frequencies start low, reach a maximum, then become low again, and are roughly symmetric about the maximum frequency. O D. No, because the frequencies are randomly distributed. O E. Yes, because the frequencies are roughly equal across the voltage classes.
