Zinc difecient Mother and birth weight problem

  1. Jun 6, 2007 #1
    Using a study of zinc deficient mothers a double blind test was conducted using a placebo group and a test group. Using a .05 significance level to test a claim that zinc supplimentation does increase weight at birth. The weights are measured in grams. How can I test to see if the zinc suplimentation effected the outcome of birth weight using the following groups of statistics:

    Zinc Supplement Group: n=294 xbar=3214 s=669

    Placebo Group: n=286 xbar=3088 s=728
