Step 2: Put the mean, μ, into the z-score equation. Step 3: Write the standard deviation, σ into the z-score equation. Step 4: Find the answer using a calculator: (1100 – 1026) / 209 = .354. This means that your score was .354 std devs above the mean.Step 2: State the Alternate Hypothesis. The claim is that the students have above average IQ scores, so: H 1: μ > 100. The fact that we are looking for scores “greater than” a certain point means that this is a one-tailed test. Step 3: Draw a picture to help you visualize the problem.
