- A medical researcher claims that the proportion of people taking a certain medication that develop serious side effects is 12%. To test this claim, a random sample of 900 people taking the medication is taken and it is determined that 93 people have experienced serious side effects.. The following is the setup for this hypothesis test: Ho :p 0.12 Ha p 0.12 In this example, the p-value was determined to be 0.124. come to a conclusion and interpret the results for this hypothesis test for a proportion (use a significance level of 5%) Select the correct answer below: The decision is to reject the Null Hypothesis. The conclusion is that there is enough evidence to reject the claim O The decision is to fail to reject the Null Hypothesis. The conclusion is that there is not enough evidence to reject the claimSome of the following statements refer to the null hypothesis, some to the alternate hypothesis.State the null hypothesis, H0, and the alternative hypothesis.
