How do I find the remaining frequencies? I believe the entire frequency distribution is 2,6,12,12,6,2, for it is a normal distribution, but I am not sure if the middle values can be equivalent. Is this correct? Can someone please explain this to me?

Question

Assume that the first two frequencies are 2 and 6 and ignore the rest of the frequencies. Assuming that it is a normal distribution with 40 sample values, determine the remaining 4 values.
Blood Count Frequency
3.0-4.9 6
5.0-6.9 16
7.0-8.9 9
9.0-10.9 7
11.0-12.9 0
13.0-14.9 2

Answer 1

The Count Frequency is located after each decimal.
Here they are individually: 6,16,9,7,0,2
