Example Problems - Show your work! A researcher knows that the weights of 6-year olds are normally distributed with u = 20 kg and o = 3.2 kg. She suspects that children in poverty-stricken regions are undernourished and therefore underweight. For a sample of n = 16 poverty-stricken children, the researcher obtains a sample mean of l8.2 kg. Use a two-tailed test and an a level of .01 to determine if this sample is reliably different from what would be expected for the general population of 6-year olds. Perform a complete hypothesis test, including a journal style summary statement. 1.
