approximately normal with no outliers and x = 8.17 cm3 and s = 0.7 cm3. Conduct the appropriate test at the a = 0.01 level of significance. to = -5.01 P-value = 0 Make a conclusion regarding the hypothesis. Reject the null hypothesis. There is sufficient evidence to claim that the mean hippocampal volume is less than _____ cm3
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 17 adolescents with alcohol use disorders to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal of 9.02 cm3. An analysis of the sample data revealed that the hippocampal volume is approximately normal with no outliers and x = 8.17 cm3 and s = 0.7 cm3. Conduct the appropriate test at the a = 0.01 level of significance.
