alcohol use disorders to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.02 cm cubed. An analysis of the sample data revealed that the hippocampal volume is approximately normal with x overbarequals8.06 cm cubed and s equals0.7 cm cubed. Conduct the appropriate test at the alphaequals0.01 level of significance.

Researchers wanted to measure the effect of alcohol on the development of a region of the brain (the hippocampus) responsible for long-term memory storage. The researchers randomly selected 12 adolescents with alcohol use disorders. They wanted to test the claim that hippocampal volumes in alcoholic teens were less than the normal volume of 9.02 centimeters cubed. An analysis of the sample data revealed that the volumes were approximately normal with a mean of 8.1 and standard deviation of 0.7. Test...
