For a study of adolescents' disclosure of their dating and romantic relationships, a sample of 208 high school students was surveyed. 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" and 5 ="always tell"). The sampled high school students had a mean disclosure score of 3.25 and a standard deviation of 1.07. 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 = 0.10. Set up Ho and Ha for testing whether the true mean disclosure score of all adolescents exceeds 3. Choose the correct answer below. O A. Hoi = 3 OB. Ho: H= 3 Hai p
