A study of the Consideration of Future Consequences (CFC) scale found a mean score of 3.20, with a standard deviation of 0.70, for the 800 students in the sample (Adams, 2012). (Treat this sample as the entire population of interest.)
a. If the CFC score is 4.2, what is the z score? Use symbolic notation and the formula. Explain why this answer makes sense.
b. If the CFC score is 3.0, what is the z score? Use symbolic notation and the formula. Explain why this answer makes sense.
c. If the z score is 0, what is the CFC score? Explain.
