Questions: The accompanying data set lists the F-scale intensities of recent tornadoes in the United States. Construct a frequency distribution. Do the intensities appear to have a normal distribution? Assume that the intensities are quantitative. Click the icon to view the F-scale intensities. Complete the frequency distribution. F-Scale Intensity Frequency 0 22 1 13 2 2 3 2 4 1 (Type whole numbers.) Do the intensities appear to have a normal distribution? A. No, because while the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, the distribution is not symmetric. B. No, because the frequencies start at a maximum and become low, and because the distribution is not symmetric. C. No, because while the distribution is approximately symmetric, the frequencies start at a maximum and become low. D. Yes, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is approximately symmetric.

(Type whole numbers.)
Do the intensities appear to have a normal distribution?
A. No, because while the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, the distribution is not symmetric.
B. No, because the frequencies start at a maximum and become low, and because the distribution is not symmetric.
C. No, because while the distribution is approximately symmetric, the frequencies start at a maximum and become low.
D. Yes, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is approximately symmetric.
