could anyone help me with the wrong answers?

Application Exercise: "Opening up" is thought to improve individuals' mood following a tragic incident. A health psychologist decided to validate this theory on PTSD patients. The psychologist collected a sample of 29 PTSD patients and asked them to talk about their PTSD related issues ("open up") with their family. The psychologist assessed the patients' level of happiness afterwards and obtained a mean of 115.17 with a variance of 24.01. The average happiness of PTSD individuals is known to be 111. What can be concluded with a = 0.10? a) What is the appropriate test statistic? One-Sample t-test b) Population: PTSD individuals Sample: PTSD patients c) Obtain/compute the appropriate values to make a decision about Ho. Critical Value = 1.3125 Test Statistic = 4.5829 Decision: Reject HO v d) If appropriate, compute the CI. If not appropriate, input "na" for both spaces below. [ 114.15 X , 116.1863 x ] e) Compute the corresponding effect size(s) and indicate magnitude(s). If not appropriate, input and/or select "na" below. d = na x ; Magnitude: na v x 1 = na X ; Magnitude: na V X f) Make an interpretation based on the results. PTSD patients that "opened up" had a significantly better mood than PTSD individuals. PTSD patients that "opened up" had a significantly worse mood than PTSD individuals. O PTSD patients that "opened up" did not have a significantly different mood than PTSD individuals
