question 30

Essay

Use the following information to answer the question. Suppose that you are a researcher and that you want to research whether a home remedy that recommends applying a salve of tobacco and saliva to cuts or scrapes to absorb toxins really works. You decide to conduct a study to see whether there is an association between the treatment and the outcome. A positive outcome means that the patient reported lower pain levels and the wound had healed without infection in less than 14 days. The table below shows the results from your study. Assume all conditions for testing have been met. $$\begin{array} { c | c | c | } \hline & \text { Home remedy } & \text { Placebo } \\ \hline \text { Positive outcome } & 52 & 23 \\ \hline \begin{array} { c } \text { Not positive } \\ \text { outcome } \end{array} & 35 & 33 \end{array}$$
-Test the hypothesis that the treatment is associated with the outcome, using a significance level of 0.05. State the correct decision regarding the null hypothesis and write a conclusion using a full sentence. Refer to the TI-83 output below. $$\begin{array} { l } \chi ^ { 2 } - \text { Test } \\X ^ { 2 } = 4.776341117 \\p = .0288533643 \\\mathrm { df } = 1\end{array}$$
