Suppose the following information is obtained by surveying residents. The mean number of children per adult is 3 with a standard deviation of 6. Assume the sample size is 64. If the national children per adult value is 1.7. calculate a Z test statistic to determine if these values are the same from a statistical perspective.  </SPAN>\n" );
