To determine whether this is a true proportion, a random sample of people are asked their eye color. Their responses are shown in the table. Eye Color Brown Blue Hazel Green Other Count 475 55 40 15 15 Which of the following represents the chi-square statistic? 475 minus 120 quantity squared all over 120 plus 55 minus 120 quantity squared over 120 plus 40 minus 120 quantity squared all over 120 plus 15 minus 120 quantity squared all over 120 plus 15 minus 120 quantity squared all over 120 475 minus 450 quantity squared all over 600 plus 55 minus 48 quantity squared over 600 plus 40 minus 48 quantity squared all over 600 plus 15 minus 12 quantity squared all over 600 plus 15 minus 42 quantity squared all over 600 475 minus 450 quantity squared all over 120 plus 55 minus 48 quantity squared over 120 plus 40 minus 48 quantity squared all over 120 plus 15 minus 12 quantity squared all over 120 plus 15 minus 42
