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 HA: m < 9.01. By doing this, we get theresults:
Hypothesis test results:
Variable | Sample Mean | Std. Err. | DF | T-Stat | P-value |
---|
var1 | 9.0091667 | 0.21260711 | 23 | -0.003919593 | 0.4985 |
2. Compute the t-value and the P-value forthis test.
