1. What are the descriptive statistics for newborn weights? Just from my personal experience with newborns, that is an unusually heavy baby.

Z = (score-mean)/SD

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to the Z score. Use that data to indicate how usual the weight is.

Hi Bob, Thanks for the direction. I got so far with it on my own and became stuck. I did as you said but still have one question. Would the answer to the question be 1.31 ounces or 6.61 ounces? I feel the answer is 1.31. Thanks *
