Do children from lower socioeconomic status (SES)neighborhoods have lower than average test-taking skills? A researcher administered a standard measure of test-taking skills to a randomly chosen child from a low-SES neighborhood and found him to have a score of 38. The average on this measure for the population in general is 50 with a standard deviation of 10. What should you conclude about whether those in low-SES neighborhoods have lower test-taking ability? (Use the .01 significance level.)
a. Use the five steps of hypothesis testing.
b. Sketch the distributions involved.
c. Explain the logic of what you did (be sure your explanation includes the overall logic of hypothesis testing, including each of the five steps).
