In aâ study, researchers wanted to measure the effect of alcohol on the hippocampalâ region, the portion of the brain responsible forâ long-term memoryâ storage, in adolescents. The researchers randomly selected 24 adolescents with alcohol use disorders to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.02 cm3. An analysis of the sample data revealed that the hippocampal volume is approximately normal with x = 8.07 cm3 and s = 0.8 cm3. Conduct the appropriate test at the level of significance.
