Researchers are trying to determine if the prevalence of CVD is different in smokers compared to nonsmokers. With this dichotomous outcome, what would be the appropriate hypothesis test to use?1. \( H_0: p_1 = p_{10}, p_2 = p_{20}, \ldots, p_k = p_{k0} \) \( H_1: H_0 \) is false (where \( p \) = proportion of participants in a specific category)2. \( H_0: m_1 = m_2 \) \( H_1: m_1 > m_2, m_1 < m_2, \text{ or } m_1 \neq m_2 \) (where \( m \) = mean)3. \( H_0: m_d = 0 \) \( H_1: m_d \neq 0 \) (\( m \) = mean)4. \( H_0: p_1 = p_2 \) \( H_1: p_1 > p_2, p_1 < p_2, \text{ or } p_1 \neq p_2 \)5. \( H_0: m_1 = m_2 = m_3 \ldots = m_k \) \( H_1: \) Means are not all equal (where \( m \) = mean)

Suppose a hypothesis test was performed with a level of significance of 0.05. Then if the null hypothesis is actually true, then there is a 5% chance that the researcher will end up rejecting the null hypothesis in error. True False
Compare statistical testing with legal methods used in a U.S. court setting. Then discuss the following topics in class or consider the topics on your own. Please write a brief but complete essay in which you answer the following questions. (a) In a court setting, the person charged with a crime is initially considered to be innocent. The claim of innocence is maintained until the jury returns with a decision. Explain how the claim of innocence could be taken to be the null hypothesis. Do we assume that the null hypothesis is true throughout the testing procedure?What would the alternate hypothesis be in a court setting?(b) The court claims that a person is innocent if the evidence against the person is not adequate to find him or her guilty. This does not mean, however, that the court has necessarily proved the person to be innocent. It simply means that the evidence against the person was not adequate for the jury to find him or her guilty. How does this situation compare with a…
If a hypothesis is rejected at significance level α = 0.01, is it possible that the hypothesis is not rejected if the same test was done at significance level α = 0.05 (with everything else staying the same)?
Acne is a common skin disease that affects most adolescents and can continue into adulthood. A study compared the effectiveness of three acne treatments and a placebo, all in gel form, applied twice daily for 12 weeks. The study's 517 teenage volunteers were randomly assigned to one of the four treatments. Success was assessed as clear or almost clear skin at the end of the 12 week period. The results of the study can be seen in the table below. Using the appropriate statistical test, determine if there is significant evidence that the four treatments perform differently. If so, how do they compare.
A newsletter publisher believes that 48 % of their readers own a laptop. A testing firm believes this is inaccurate and performs a test to dispute the publisher's claim. After performing a test at the 0.10 level of significance, the testing firm fails to reject the null hypothesis. What is the conclusion regarding the publisher’s claim?
You come across Professor Cafferty's data set from his Master's thesis and realize that he has data on types of family support that 26 homosexual men had during young adulthood (about 18-25 years old). You come across two questions where the respondent was asked if they would identify their family as religious and whether or not they received financial support from their family. Please complete the appropriate 8-step hypothesis test using the data below. Had Financial Support Did Not Have Financial Support Family Religious 3 12 Family Not Religious 6 5
Over the past few decades, public health officials have examined the link between weight concerns and teen girls' smoking. Researchers surveyed a group of 273 randomly selected teen girls living in Massachusetts (between 12 and 15 years old). After four years the girls were surveyed again. Sixty-three said they smoked to stay thin. Is there good evidence that more than thirty percent of the teen girls smoke to stay thin? Correctly identify the null and alternative hypotheses:
Answer the following True or False: Suppose a hypothesis test was performed with a level of significance of 0.05. Then if the null hypothesis is actually true, then there is a 5% chance that the researcher will end up accepting the alternative hypothesis in error. false true
What is the Null & Alternative Hypothesis? and what type of analysis you would use to test the hypothesis in your study?
A newsletter publisher believes that 29% of their readers own a laptop. Is there sufficient evidence at the 0.05 level to refute the publisher's claim? State the null and alternative hypothesis for the above scenario
A new anxiety medication has been manufactured and a study is being conducted to determine whether its effectiveness depends on dose. When 40 milligrams of the medication was administered to a simple random sample (SRS) of 60 patients, 21 of them demonstrated lower stress levels. When 75 milligrams of the medication was administrated to another SRS of 85 patients, 34 of them demonstrated lower stress levels. Which of the following test statistics is an appropriate hypothesis test?
