Dating and disclosure. Refer to the Journal of Adolescence

(Apr. 2010) study of adolescents’ disclosure of their dating and romantic relationships, Exercise 1.33

(p. 51). Recall that a sample of 222 high school students was recruited to participate in the study. One of the variables of interest was the level of disclosure to an adolescent’s mother (measured on a 5-point scale, where 1 = “never tell,” 2 = “rarely tell,”

3 = “sometimes tell,” 4 = “almost always tell,” and 5 = ”always tell”). The sampled high school students had a mean disclosure score of 3.26 and a standard deviation of

.93. The researchers hypothesize that the true mean disclosure score of all adolescents will exceed 3. Do you believe the researchers? Conduct a formal test of hypothesis using a = .01.
