.2.21 Question Help * 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 27.7 volts, and use a class width of 0.2 volt. Does the result appear to have a normal distribution? Why or why not? 囲Click the icon to view the data. 128.1-128.2 128.3-128.4 128.5-1286 10 Type integers or decimals rounded to the nearest tenth as needed.) Does the result appear to have a normal distribution? Why or why not? O A. No, because the frequencies are roughly equal across the voltage classes O B. No, because the frequencies are not equal across the voltage classes O C. No, because the frequencies are randomly distributed 0 D. Yes, because thefrequencies are roughly equal across the voltage casses ○ E. Yes, because the frequences start low, reach a manum, then become low agan, and are roughly symmetrie about me mas mum frequency. ES ook
