A certain country's government claims that based on the results of their COVID-19 responsesatisfaction survey in 2020, 25% of their citizens claim that they are satisfied with theirgovernment's response to the pandemic. In 2021, the survey was conducted again and out of asample of 6,000 respondents, 1,575 showed satisfaction with the government's efforts. At a 0.05level of significance, is there evidence that the satisfaction rate of the citizens improved (higher)from 2020 to 2021?(a) What is an appropriate Null Hypothesis for the situation?

An organization published an article stating that in any one-year period, approximately 11.5 percent of adults in a country suffer from depression or a depressive illness. Suppose that in a survey of 100 people in a certain town, nine of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult population in the country. At a pre-conceived α = 0.05, what are your following?Decision: , Reason for the decision: ,Conclusion

The number of Muslims continues to grow throughout the world, and they are currently thesecond-largest religious group in the world. Knowing that this group has been the target of falsebeliefs about their religion, a researcher is interested in whether people who have moreinteractions with Muslim people are less likely to believe negative statements about Islam. To dothis, they surveyed a large sample of participants across Western Europe and asked themquestions about how frequently they interact with Muslim people as well as how much theyagreed with negative statements about Islam. What statistical test should be used to determine ifthere if how frequently survey participants interact with Muslim people predicts how likely theyare to agree with a negative statement about Islam? Assume parametric assumptions are met. A. Is this a relationship test or a difference test? Explain your rationale. B.
