   Question

   We derived the following figures for the variable ‘age’ from a random sample: number of respondents 200, mean 46.1340, standard error 0.11751, standard deviation 1.66179.

   What is the z-score of a 44 year old person?

   
   
   1. TRUE: (44-46.1340)/1.66179
   2. FALSE: (46.1340-44)/1.66179
   3. FALSE: (44-46.1340)/0.11751
   4. FALSE: (44-46.1340)/2.762
   
   

   Solution

    formula z = (x - μ) / σ where x is your data point, μ is the mean, and σ is the standard deviation

   
   
   1. True
   2. False
   3. False
   4. False
