Question

State the null and alternative hypotheses
Calculate the expected results for the hypothesis test assuming the null hypothesis is true and determine the hypothesis test model , i.e., “cut-off” critical values etc.
Formulate the decision rule, i.e., include “one-tail ”left, or “one-tail” right, or “two-tail” determination etc.
Determine the experimental outcome.
Determine the conclusion, and answer the question(s) posed in the problem, if any.

The mean score on a standardized psychology test is supposed to be 50. Believing that a group of psychologists will score higher, we test a random sample of 11 psychologists. Their mean score is 45 with s=3. Test at a 1% level of significance.
