What type of study design is this? B) Conduct a paired sample t test investigating the effectiveness of the new therapy technique with 95% confidence. Write out your null and alternative hypotheses, and interpret your pvalue correctly. C) Construct a 95% confidence interval representing the average difference in score on the GDS. Provide an accurate interpretation of your interval.
Suppose a researcher is interested in the effectiveness of a new novel talk therapy technique in reducing overall depression as identified via score report on the geriatric depression scale (GDS). In order to carry out this hypothesis, the researcher gathers a SRS of participants in the program and performs the GDS test prior to, and after initiation of the new therapy technique. Assume the SRS score report presented below represents an approximately normal distribution.
