Referring again to the table above of LBW by Race, we want to know if the proportion of LBW births to white women is significantly different from the proportion of LBW births to women of race "other", based on a =0.05 test.

1. Is this question calling for a 2-sided test? (yes or no)
2. What is the test statistic, based on the pooled standard error? (Report with 2 decimal places, such as 1.23 or -1.23)
3. Does this Z-statistic indicate the two proportions are significantly different from each other, based on no more than a 5% chance of a type 1 error (alpha = 0.05)? (yes or no)
