A table represents the possibility of an association between eye color and hair color. Hair Color Eye Color Brown Black Green 22 15 Blue 18 19 In order to determine if there is a significant difference between eye color and hair color, the chi-square test for association and independence should be performed. What is the expected frequency of Blue Eyes and Black Hair?

17

Step-by-step explanation:

Hair color

Eye color ___ Brown ___ Black ___ total

Green 22 15 37

Blue 18 19 37

Total 40 34 74

Calculate the expected frequency of Blue Eyes and Black Hair?

The expected frequency Count ;

(row total * column total) / total number of observations

Expected frequency ;

Blue eye n black hair = (37 * 34) / 74

Expected frequency count = 1258 / 74 = 17

Expected count = 17

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
