To perform one sample Z tests
In a recent national survey, the mean weekly allowance for a nine-year-old child from his or her parents was reported to be $3.65. A random sample of 45 nine year olds in northwestern Ohio revealed the mean allowance to be $3.69 with the standard deviation of .24. At .05 level of significance is there a difference in the mean allowances nationally and mean allowances in northwestern Ohio for nine-year-olds?
