A researcher has compiled a file of information on a random sample of 317 families that have chronic, long-term patterns of child abuse. Reported below are some of the characteristics of the sample, along with values for the city as a whole. For each trait, test the null hypothesis of "no difference." You must state your hypotheses; compute the test statistic; and explain your decision for each. **For at least one of the following problems, conduct both a one-tailed and a two-tailed test. For the other problems, a two-tailed test is fine.**
