Question 381262: Suppose we are interested in testing whether the mean value for the number of children per adult matches the national value for the same variable. 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. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! 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
-----------
