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 24 adolescents with alcohol use disorders to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.02 cm. An analysis of the sample data revealed that the hippocampal volume is approximately normal with no outliers and x bar=8.12 cm and s= 0.7 cm. Conduct the appropriate test at the 0.01 level of significance. Identify the P-Value and whether or not the null needs to be rejected or accepted.

Expert Solution
P value = 0.00
As p value < alpha
We reject the null hypothesis.

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 19 adolescents with alcohol use disorders to determine
whether the hippocampal volumes in the alcohol 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 x=8.06 cm3 and s=0.7 cm3.

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...
