Explain. Frequency Frequency Temperature (°F) 40-44 45-49 50-54 55-59 Temperature (°F) 60-64 65-69 70-74 Choose the correct answer below. OA. Yes, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is approxima symmetric OB. Yes, because the frequencies start low, proceed to one or two high frequencies, then increase to a maximum, and the distribution is not symmetric. OC. No, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is not symmel OD. No, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is approxima symmetric Click to select your answer and then click Check Answer.

Answer 1

Clearly the frequencies are starting from lower value 1 and increasing in a constant rate upto a highest frequency of 14 and then again decreasing in the same rate to the lower frequency of 1.

If we draw a bar diagram with the frequency we will get

14 1.

Which shows that the distribution is approximately symmetric.

So the correct option is  A
