Question

3) In a study published by the American Journal of Psychiatry (May 2019) researchers wanted to measure the effect of alcohol on the hippocampal region of the brain in adolescents. 12 adolescents who use alcohol were randomly chosen. Hippocampal volumes were examined. The mean hippocampal volume for the whole population is 9.03 cubic centimeters. An analysis revealed that the mean hippocampal in the 12 chosen subjects was 8.1 cubic centimeters with a standard deviation of 0.7 cubic centimeters. At the 1% level of significance, can it be concluded that the adolescents have a lower hippocampal volume?
