In a study. researchers wanted to measure the effect of alcohol on the hippocampal region. the portion of the brain responsible for longterm memory storageI in adolescents. The researchers randomly selected 1? 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 no outliers and = 3.1TIr cmEl and s = 0.8 cm3. Conduct the appropriate test at the ct = 0.01 level of signicance. State the null and alternative hypotheses. H0:p Y H1: p Y (Type integers or decimals. Do not round.) ldenti y the tstatistic. = (Round to two decimal places as needed.) ldenti y the Fvalue. Pvalue = (Round to three decimal places as needed.) Make a conclusion regarding the hypothesis. V the null hypothesis. There V sufficient evidence to claim that the mean hippocampal volume is V cm
