Activity 11 -Confidence intervals and hypothesis tests

Conduct a hypothesis test to see if the zyban only treatment produces a statistically signicant result. Assume the population proportion of success for the placebo treatment is 19%. - v Determine the null and alternative hypotheses. A. 6.306 _ v What is the numerical value for the sample proportion? B. H0: p = 0.] 9 (That is, what is the standardized score or zscore?) H a: p 4 0.19 - v ' _ 9 What is the p value. C. 1.442 ' v What 15 the \"MI\"S'M? Justify yoar eonclusron. D. Reject the null hypothesis because the p-value is less than 0.05. The zyban only treatment is effective. 5- o (1.442r10'1=o.oooooooom442=0) F. 1-10: p = 0.] 9 Ha: p > 0.19 G. Do not reject the null hypothesis because the p-value > 0.05. The zyban only tteatment is not e'ective.
