It is claimed that the average age of working students in Paranaque City College is 25 years. A researcher selected at random a sample of 15 working students. The computed average age was 28 years with a standard deviation of 5 years. Does the average age of the working a student is different from 25 years? Use 0.15 level of significance and assume normality in the population. Solution: Step 1: State the hypothesis and identify the claim. Ho: p (claim) Ha: p Step 2: Find the critical values. The critical values are , for o = __ and d.f. = , since the altemativa hypothesis uses #, it refers to test.
