Anyone has Idea on Chi Square

  1. Apr 19, 2007 #1
    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.

    This forum isn't for homework questions. If you're trying to get questions answered at least show your attempts at the questions. No-one is going to give you the answer straight up, but someone may give you some guidance if you show an attempt that is heading in the right direction
