Does the frequency distribution appear to have a normal distribution? Explain.

Temperature Frequency Temperature Frequency

(degrees° F) (degrees° F)

35-39 11 55-59 10

40-44 4 60-64 3

45-49 10

50-54 15 65-69 1

A. 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.

B. No, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is not symmetric.

C. Yes, because the frequencies start low, proceed to one or two high frequencies, then increase to a maximum, and the distribution is not symmetric.

D. No, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is approximately symmetric.

Option C is the answer

Step-by-step explanation: a normal distribution is always not symmetric, from the table above, the mode median and mean are almost equal.
