Transcribed Image Text:Researchers wanted to measure the effect of alcohol on the development of the hippocampal region in adolescents. The researchers randomly selected 13 adolescents with alcohol use disorders. They wanted to determine whether
the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.02 cm. An analysis of the sample data revealed that the hippocampal volume is approximately normal with x= 8.17 ands=0.6. Conduct
an appropriate test at the a= 0.05 level of significance.
Choose the correct hypotheses.
Ho
9.02
V9.02
Find the test statistic.
