Stat question

QUESTION 13 Based on excellent research above, the research team then receives funding to conduct a small pilot study examining the effects of a new diversion program operated by a local police agency. The program diverts individuals using drugs to treatment programs rather than arresting and prosecuting them for non-violent drug crimes. The researchers collect information about 20 individuals that followed arrest-prosecution path (sample 1) and 20 individuals that were diverted to drug treatment programs (sample 2) using a random sample methodology and random assignment. They present the mean number of times an individual used illegal drugs for each group (along with the group standard deviation and sample size). Does the frequency in drug use differ significantly at the .01 level of significance between arrest-prosecution group and the treatment group? Follow the ypothesls testing framework and show all steps and work. Set alpha = .01. Sample 1 - Arrest-Prosecution Sample 2 - Treatment Diversion prf=22.2 szll.2 s = 18.0 s = 16.0 N = 20 N = 20 Note to compute the t-obtained: '71: = 5 -5 (\"standard error of the difference between means") QUESTION 14 Examine the study results and your decision closely from the previous question. You've made a decision about the null hypothesis and statistical significance. What does it mean when we call a difference "statistically significant" (or "not statistically significant") in this kind of context? In your response, be sure to differentiate it from the concept of a "substantively important" or "meaningful" difference? Explain these concepts in connection to the scenario
