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 of dating and romantic relationships 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 0.93. 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 = 0.01. (1) Critical Value (Round off to 3 decimal places): (2) Test Statistic (Round off to 2 decimal places): (3) Conclusion: |(Type 'Reject HO' or 'Fail to Reject HO')
