For all the Hypothesis Testing problems, include the hypotheses (label the claim), a sketch of the sampling distribution indicating the direction of the test, test statistic, and Pvalue. State your decision, and separately, give an interpretation in the context of the original claim. Medical professionals are concerned about the effect that prescription opioid use has on patients. One of the reasons they are concerned is because of the possible risk that patients will switch to more dangerous drugs, specifically heroin. However, the link between prescription opioid abuse and heroin use is not fully known. An activist who is especially concerned about this connection claims that more than $7\%$ of prescription opioid abusers move on to heroin. However, according to a study among 350 randomly selected opioid abusers, $4\%$ eventually began using heroin. Test the activist's claim using the results of this study. Use a level of significance of $?=$ 0.05
