Using the table, How would you write the results for the statistically significant improvements in caregiver stigma relating to overmedication ?
Adverse reactions of a drug used to help patients continue their abstinence from the use of alcohol have been studied in clinical trials, and the accompanying table summarizes results for digestive system effects among patients from different treatment groups. Use a 0.05 significance level to test the claim that experiencing an adverse reaction in the digestive system is independent of the treatment group. Does the drug treatment appear to have an effect on the digestive system? Click the icon to view the data on adverse reactions from treatments. Determine the null and alternative hypotheses. OA. Ho: Drug treatment and adverse effects are not independent. H₁: Drug treatment and adverse effects are independent. OB. Ho: The drug treatment results in adverse effects on the digestive system. H₁: The drug treatment does not result in adverse effects on the digestive system. OC. Ho: Drug treatment and adverse effects are independent. H₁: Drug treatment and adverse effects are not…
