Solution

H0: Blue and white are entirely same

Ha: There is no association or equality between blue and white

Two sided chi square test.

Two-way Contingency Table

?2 = 40.551,     df = 2,     ?2/df = 20.28 ,         P(?2 > 40.551) = 0.0000

As p value =0

H0 is rejected.

Blue and white are different.

warning:  some observed or expected frequencies are less than 5; thus the Central Limit Theorem may not apply and the resultant ?2 may be invalid

expected values are displayed in italics
individual ?2values are displayed in (parentheses)
