Say I have ranges:(adsbygoogle = window.adsbygoogle || []).push({});

(-infinity to 16) where the observed frequency is 35

(16 to 18) where the obs freq is 100

(18 to 20) where the obs.. freq. is 360

(20 to 22) where the obs. freq. is 326

(22 to 24) where the obs. freq. is 150

(24 to infinity) where the obs freq is 29

The mean is 20 and standard deviation is 2

How would i find the expected value of each range?
