Begin with a lower class limit of 121.1 volts, and use a class width of 0.2 volt Does the result appear to have a normal distribution? Why or why not? Click the icon to view the data. Complete the frequency distribution below. olts 121.1- (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. O B. ° C. 0 D. O E. No, because the frequencies are randomly distributed. Yes, because the frequencies are roughly equal across the voltage classes. No, because the frequencies are not equal across the voltage classes. No, because the frequencies are roughly equal across the voltage classes. Yes, because the frequencies start low, reach a maximum, then become low again, and are roughly symmetric about the maximum frequency Click to select your answer(s).

Explanation / Answer

frequency distribution

And the given frequency distribution is not normally distributed. Because roughy all the frequencies are equal (5) along with the voltage class.

Option D is correct answer

Voltage (Class) Frequency 121.1- 121.3 6 121.3- 121.5 5 121.5- 121.7 4 121.7- 121.9 5 121.9- 122.1 5
