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.

An astronomer is testing the claim that the mean brightness of a certain star is now more than 30 units. The astronomer is able to get 6 readings on the star during an experiment as shown in the table. Using a 1% level of significance, does this indicate a new mean brightness of more than 30?
