MATH 225N: Week 7 Assignment Developing Hypothesis and understanding Possible Conclusion for Proportions (Q&A) Latest Update. Identify the null and alternative hypotheses for an experiment with one population proportion Question Devin is a researcher for a pharmaceutical company testing whether a new prescription pain medication causes patients to develop nausea. The medication would have to be scrapped if more than 6% of patients who take the medication develop nausea on a regular basis. Devin randomly selected 461 patients for a clinical trial of the medication and found that 27 of the patients developed nausea on a regular basis. What are the null and alternative hypotheses for this hypothesis test? {H0:p=0.06Ha:p0.06 First verify whether all of the conditions have been met. Let p be the population proportion for patients taking the medication who develop nausea on a regular basis. 1. Since there are two independent outcomes for each trial, the proportion follows a binomial model. 2. The question states that the sample was collected randomly. 3. The expected number of successes, np=27.66, and the expected number of failures, nq=n(1−p)=433.34, are both greater than or equal to 5. Since Devin is trying to determine whether more than 6% of the patients taking the medication develop nausea on a regular basis, the null hypothesis is that p is equal to 0.06 and the alternative hypothesis is that p is greater than 0.06. The null and alternative hypotheses are shown below. {H0:p=0.06Ha:p0.06 Great work! That's correct. Compute the value of the test statistic (z-value) for a hypothesis test for proportion Question A college professor claims that the proportion of students passing a statistics course is 80%. To test this claim, a random sample of 250 students who previously took the course is taken and it is determined that 221 students passed the course.
