1. Assume that the mean adjusted hippocampal volume for healthyadolescents is 9.01 cubic centimeters. State the hypotheses to testwhether the AOAUD mean hippocampal volume is less thanthis value.
To perform the hypothesis test, we will compute H₀: m= 9.01 and H_A: m < 9.01. By doing this, we get theresults:
