For a study of adolescents' disclosure of their dating and romantic relationships, a sample of 236 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 3.34 and a standard deviation of 0.78. 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. Set up H, and H, for testing whether the true mean disclosure score of all adolescents exceeds 3. Choose the correct answer below. O A. Ho: H=3 O B. Họ: H=3 c. Họ: H=3 O D.

Can you answer C and is the null hypothesis rejected??

For a study of adolescents' disclosure of their dating and romantic relationships, a sample of 236 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 3.34 and a standard deviation of 0.78. 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.
Set up Ho and H, for testing whether the true mean disclosure score of all adolescents exceeds 3. Choose the correct answer below.
A. Ho: μ 3
B. Ho: H= 3
Ha: H<3
Ha: H#3
D. Ho: H#3
HaiH= 3
C. H: μ=3
Ha: µ> 3
If a = 0.01, find the rejection region for the test. Choose the correct answer below.
A. z>2.575
B. z> 2.33 or z< - 2.33
C. z>2.33
D. z< - 2.575
O E. z> 2.575 or z< -2.575
O F. z< -2.33
