[sumans]

The following table shows brand preferences against gender on the basis of a random sample of size 100 from population. It is intended to examine possible association between gender and brand preferences.

Brand A Brand B
Men 30 20
Women 20 30

At 5% level of significance will you conclude that gender and brand preferred are independent? It is given that the table value of the Chi-Square distribution with right tail area equal to 5% for 1, 2 and 3 degrees of freedom are 3.84, 5.99 and 7.81 respectively.
