   Question

   Young men in a population have an average height of 170 cm and a standard deviation of 6.75 cm. Young women have a mean height of 160 cm and a standard deviation of 6.25 cm. Both distributions are approximately normal. A young man and a young woman are chosen at random. Which answer describes the sample distribution the difference in height between the chosen man and the chosen woman?

   
   
   1. FALSE: This sample distribution is a normal distribution with a mean of 10 and a standard error of 0.50.
   2. TRUE: This sample distribution is a normal distribution with a mean of 10 and a standard error of 9.20.
   3. FALSE: This sample distribution is a normal distribution with a mean of 165 and a standard error of 13.
   4. FALSE: This sample distribution is a normal distribution with a mean of 101.9 and a standard error of 13.
