• The CBCL measures children's behavior. Lower scores indicate better behavior. The mean CBCL score in the population is μ = 50. • Thirty children in a third-grade class were scored on the CBCL, and their mean score was X = 39.33 and the group's standard deviation was ŝ = 10.51. Are these children different from the population standard of μ = 50? • o State the null hypothesis, choose an alternative hypothesis, perform a t test, calculate d, and write a conclusion.
