Question

suffering from severe depression, patients were divided into two groups, one receiving St John's wort (sample 1), the other receiving a placebo. The results were examined as follows, where X number in remission in the group. (Assume that sample sizes are big enough to justify a normal approximation approach.) Sample p 1 14 98 0.1 428 57 14 2 5 102 0.049 01961 2-sample test for equality of proportions without continuity correction data c (14, 5) out of c (98, 102) z-statistic 2.2625 p-value 0.01 183 alternative hypothesis greater 95 percent confidence interval: 0.02588884 1. 00000000 sample estimates prop 1 prop 2 0.14285714 0.04901961 Wechat

Explanation / Answer

95% confidence interval =0.01287167 to 0.17480340

In percentage it is (1.3% to 17.5%) up to one decimal.

So, we can say with95% confidence.

Since it right tailed test(as given alternative hypothesis is greater) that the proportion in remission for those using..........

............. taking placebo.
