Do Children Raised in a Communal Environment Differ from Children

Essay

Do children raised in a communal environment differ from children in general in their ability to recognize emotional expression? A standard test of emotional expression shows a series of pictures of various facial expressions. In this series, the average child in the population in general can identify 14 with a standard deviation of 3. The researcher administers the picture test to a randomly selected child raised in a communal environment. The child was able to identify 16 expressions correctly. Based on this result, what should you conclude about whether being raised in a communal environment makes any difference in children's ability to recognize emotional expression? (Use the .01 level.)
a. Use the five steps of hypothesis testing.
b. Sketch the distributions involved.
c. Explain the logic of what you did (be sure your explanation includes the overall logic of hypothesis testing, including each of the five steps).
