In a study, researchers wanted to measure the effect of alcohol on the hippocampal region, the portion of the brain responsible for long-term memory storage, in adolescents. The researchers randomly selected 21 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 analy of the sample data revealed that the hippocampal volume is approximately normal with no outliers and x=8.08 cm³ and s=0.8 cm³. Conduct the appropriate test at the a=0.01 level of significance. State the null alternative hypotheses H₂H H₁: p (Type integers or decimals. Do not round.) Identify the t-statistic to=(Round to two decimal places as needed.) Identify the P-value P-value (Round to three decimal places as needed.) Make a conclusion regarding the hypothesis. the null hypothesis. There sufficient evidence to claim that the mean hippocampal volume is C
