Scenario: Erna Economist claims that a majority of Americans feel that corporations make too much profit. According to a 2019 Pew Research poll, 56% of a random sample of 1,500 adults said that business corporations make too much profit. Run a hypothesis test to assess Erna Economist's claim. Question: Given the p-value you calculated, which of the following is a correct conclusion for this test? (select all that apply) Because p < a, we can reject the null hypothesis. Because p > a , we fail to reject the null hypothesis. O There is support for the alternative hypothesis. There is no support for the alternative hypothesis. There is support for Erna Economist's claim. There is no support for Erna Economist's claim.

Hypothesis testing will consist of four hypothesis tests which you need to complete. each test will require the following: Type of Test: Null Hypothesis: Alternate Hypothesis: SE: Test Statistic: P-value: Decision: Sentence:

a) What is the correct p-value for this test?

A news article that you read stated that 54% of voters prefer the Democratic candidate. You think that the actual percent is larger. 129 of the 212 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.10 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? v| Select an answer v (please enter a decimal) H1:|? v|| Select an answer v (Please enter a decimal) c. The test statistic ? v (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? v a f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the population proportion is not significantly larger 54% at a = 0.10, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 54%. O The data suggest the…

In 1970, 590 students among 1000 randomly selected college freshmen thought that capital punishment should be abolished. In 2005, 350 students among 1000 randomly selected college freshmen thought that capital punishment should be abolished. What is the two-sample z test statistic for evaluating the null hypothesis that the percentage of students who support capital punishment did not change from 1970 to 2005? Round your answer to two decimal places.

Hypothesis Test: Perform the specified hypothesis test. Be sure to include your statistical andin-context conclusion statements. In 1994, 52% of parents with children in high school felt it was a serious problem that high schoolstudents were not being taught enough math and science. A recent survey found that 512 of 1000 parentswith children in high school felt it was a serious problem that high school students were not being taughtenough math and science. Do parents feel different today than they did in 1994? Use the α = 0.005significance level.

According to the most recent General Social Survey, 70% of adults watch TV nightly. A researcher believes that the proportion of college students who watch TV nightly is less than this. To test this claim the research samples 400 college students and finds that 276 watch TV nightly. At the 0.05 level of significance does this data provide evidence to suggest that the proportion of college students who watch TV nightly is less than 70%? What is the p-value for this hypothesis test? Round to three decimal places.

Last year, 46% of business owners gave a holiday gift to their employees. A survey of business owners indicated that 40% plan to provide a holiday gift to their employees. Suppose the survey results are based on a sample of 60 business owners. Suppose the business owners in the sample do as they plan. Compute the p value for a hypothesis test that can be used to determine if the proportion of business owners providing holiday gifts has decreased from last year. If required, round your answer to four decimal places. If your answer is zero, enter “0”. Do not round your intermediate calculations.

A university has decided to introduce the use of plus and minus grading as long as there is evidence that 60% of the faculty is in support of this change. Write an appropriate null hypothesis and alternate hypothesis to test if the proportion is greater than 60%.
