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 claim
According to the Pew Research Center, 19% of U.S.adults living in Rural areas of the country do not use the internet. An SRS of 400 adults from Rural areas in Oregon had 65 indicate they do not use the internet. Given alpha = 0.05 , is there evidence to support that 19% of adults living in Rural Oregon do not use the internet? True or False. Since the alternative hypothesis uses a not equal sign this is a one sided test.

A new drug to treat psoriasis has been developed and is in clinical testing. Assume that those individuals given the drug are examined before receiving the treatment and then again after receiving the treatment to determine if there was a change in their symptom status. If the initial results showed that 3.0% of individuals entered the study in remission, 74.0% of individuals entered the study with mild symptoms, 13.0% of individuals entered the study with moderate symptoms, and 4.0% entered the study with severe symptoms calculate and interpret a chi-squared test to determine if the drug was effective treating psoriasis given the information below from the final examination. Remission (No Symptoms of Psoriasis) Mild Symptoms of Psoriasis Moderate Symptoms of Psoriasis Severe Symptoms of Psoriasis Total Number of Participants to Receive the Drug Number of Participants 455 635 85 7 1182
An article published in the “American Journal of Public Health” describes the results of a health survey administered to 119 male convicts, 50 years of age or older, residing in a state social rehabilitation center. It was found that 21.6% of them claimed to have a history of venereal diseases. Based on these findings, we wish to evaluate whether more than 15% of this population has a history of venereal diseases. After evaluating the information, what would be the conclusion? A. In the population of male convicts aged 50 years or older, residing in the state social rehabilitation center, more than 15% have a history of venereal diseases. B. In the population of male convicts aged 50 years or older, residing in the state social rehabilitation center, it is not possible to say that more than 15% have a history of venereal diseases. C. In the population of male convicts aged 50 years or older, residing in the state social rehabilitation center, on average more or less 21.6% have a…
