Question
Can a chi-square analysis be performed on the above table?
(A) Yes, because at least one of the observed frequencies is less than 5. (B) No, because the population is not normal. (C) Yes, because only some of the expected frequencies are less than 5. (D) No, because at least one of the observed frequencies is less than 5. (E) Yes, because all of the observed frequencies are at least 5. (F) No, because at least one of the expected frequencies is less than 5. (G) Yes, because at least one of the expected frequencies is less than 5.
E and G both are incorrect!!!

Data from adoption studies on handedness indicate that the effects of shared biological heritage are more powerful determinants of hand preference than sociocultural factors. Biological offspring were found to show nonrandom distributions of right and non-right handedness as a function of parental handedness. In contrast, the handedness distribution of adopted children as a function of parental handedness was essentially random. The following table gives the handedness of bi al offspring as a function of parental handedness. Biological Offspring Parental Handedness Right-Handed Left-Handed (father x mother) Right x Right Right x Left 307 29 16 37 Left x Right 6Explanation / Answer
here option D is correct
cause for right left and left handed cell ; left right and left handed cell expected values is less than 5
