A researcher is studying a possible relationship between eye color and vision. The eye colors studied are blue and brown. Quality of vision is separated into three categories: poor, average, and good. The following is the frequency matrix from the sample. What is the chi-square statistic for the study?

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
