The study of immigrant women and their adult daughters mentioned in the text also separated the data into 580 mother-daughter pairs where the adult daughter lived in the same ZIP code she was born in and 3,541 pairs where the daughters moved to a different ZIP code. For the 580 daughters who stayed, the difference in ZIP-code percentile had a mean of −2.5775 and a standard deviation of 8.1158. For the 3,541 daughters who moved, the difference in ZIP-code percentile had a mean of 4.3066 and a standard deviation of 27.6117. For each of these two data sets, calculate the two-sided P value for testing the null hypothesis that the mean is 0. Compare your results.
