Question 381262
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. 
------
z(3) = (3-1.7)/(6/sqrt(64)) = 1.7333
