The number of people in each subgroup was not readily available in the article, but we'll use the following table as an estimate. Younger Americans (ages 18 to 29) Americans with Americans college degrees sample size know a recent immigrant 3100 1200 600 24% 33% 36% For both of the following, clearly label the steps of your hypothesis test, including • Stating the null and alternative hypotheses. Both of the following scenarios should be two-tailed tests. • Determining the mean and standard error of the sampling distribution based on the null hypothesis Calculating the p-value for the sample statistics • Drawing conclusions in both statistical language and common language tied to the original context. Part A: Conduct a hypothesis test for the null hypothesis that the proportion of Americans who know a recent immigrant is the same for Americans with college degrees and Americans in general. Part B: Is there a difference in the chance an American will know a recent immigrant depending on whether that American is a college graduate or a younger American? Conduct a hypothesis test and explain your results in common language.

Use the study below for Part A, Part B, and Part C. A soft drink company surveys 500 shoppers and finds that 61% of shoppers prefer diet soda to regular soda.

Show your work and round to the nearest hundredth.Part B: If the sample size would increase to 1,000 respondents while keeping the rest of the variables the same, what would happen to the margin of error?Part C: Support your answer to Part B by finding the margin of error if 1,000 shoppers were surveyed while keeping the rest of the variables the same.

Solve the following problems. Use the steps in conducting hypothesis tests.Adults aged 18 years old and older were randomly selected for a survey on obesity. Adults are considered obese if their body mass index (BMI) is at least 30. The researchers wanted to determine if the proportion of women who are obese in the south is less than the proportion of southern men who are obese. The results are shown in Table. Test at the 1% level of significance. PS: The picture is below

If sample data is such that for a one-tailed test of ? you can reject H0 at the 1% level of significance, can you always reject H0 for a two-tailed test at the same level of significance? Explain your answer? A. Yes. If H0 for a one-tailed test is rejected at the 1% level of significance, it will always be rejected for a two-tailed test at the same level of significance. B. No. If H0 for a one-tailed test is rejected at the 1% level of significance, it will never be rejected for a two-tailed test at the same level of significance. C. Yes. The P-value for the two-tailed test could be greater than 0.01. D. No. The P-value for the two-tailed test could be greater than 0.01.
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
The average income of a large sample of households is $63,000 and the s.d. is $7,000. Assume that the data is approximately bell-shaped. What percent of these households have incomes between $42,000 and $77,000? Don’t forget to properly justify your answer using the empirical rule.
Hi, may you please help me with the following: The purpose of this assignment is to apply hypothesis tests to the case of Bayview University. Use the dataset below and read the case thats attached, use descriptive statistics to summarize the data and comment on your findings. Answer the following 3 questions. Develop 95% confidence interval for the proportion of all students, the proportion of male students, and the proportion of female students who were involved in some type of cheating. Conduct a hypothesis test to determine whether the proportion of business students at Bayview University who were involved in some type of cheating is less than that of business students at other institutions by the Chronicle of higher education. Conduct a hypothesis test to determine whether the proportion of business students at Bayview University who were involved in some form of cheating is less than that of nonbusiness students at other institutions are reported by the Chronicles of Higher…

I am asking for help on the second question: "Identify whether each of the following..." and the first two bullet point that follow it starting with "Researchers are studying..." and ending with "A study tracks the long-term..."
Part 3: Putting the Pieces Together Some of the following questions might be more challenging, but we want you to wrestle through them and ask for clarification along the way. We hope that, ultimately, working through these problems will strengthen your understanding of the big ideas behind confidence intervals. 10. A researcher plans to survey a random sample of undergraduate students in order estimate the proportion of all undergraduate students who plan to apply to graduate school, and she will construct a confidence interval based on the data she gathers. Which one of the following combinations of sample size and confidence level will result in the most precise confidence interval? A.n= 500, confidence level = 95% B. n = 500, confidence level = 90% c.n= 1000, confidence level = 99% D. n 1000, confidence level = 90% E.n=200, confidence level = 99% 11.
