Test: Test 1 Submit Test This Question: 15 pts This Test: 60 pts possible Refer to the accompanying data set and use the 25 home voltage of 121.5 volts, and use a class width of 0.2 volt Does the result appear to have a normal distribution? Why or why not? EEB Click the icon to view the data Complete the frequency distribution below 121.5-121.7 (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 B. No, because the frequencies are roughly equal across the voltage classes. O C. No, because the frequencies are not equal across the voltage classes O D. Yes, because the frequencies start low, reach a maximum, then become low again, and are roughly symmetric about the maximum frequency O E. No, because the frequencies are randomly distributed Click to select your answer(s)Explanation / Answer
The frequency table is as follows:
The result appears to have a normal distribution because extreme values on the either side have low frequency. Also, if we plot it on a graph, we get a normal like curve.
Answer: D
Yes, because the frequencies start low, reach a maximum, then become low again
