Since the last question got rejected, I will post the same one, but have points illustrated. It's basically asking you to choose one or the other; Are, or are not; High, or low; is, or is not.
A large juice company that manufactures only apple juice surveyed customers at a local grocery store. Five mothers of young children were asked if they give their children apple juice or orange juice. Before each survey, the interviewer stated that their apple juice was healthier than orange juice. Out of the five mothers surveyed, four of them prefer to give their children apple juice instead of orange juice. Which of these conclusions is most likely true? A. The survey given to the mothers is a fair, non-biased survey. B. The juice company can legitimately use this survey to promote drinking apple juice instead of orange juice. C. The survey is much too small to have any real implications for choosing apple juice instead of orange juice. D. If 100 mothers are surveyed, exactly 80 of them will recommend giving apple juice to children instead of orange juice.
George is applying for a company that requires either a P test or an A test.The company sends only 1 test result.He has acquired scores on both the tests.he has scored 98 on the P test and 112 on the A test.which test results will he most likely to submit.??is this information enough to convince George on submitting his chosen test result .?? Why??
Suppose we have a study OR = 2.00 and the investigators state they feel the result is biased towards the null. This means the true OR, in the opinion of the investigators, is: Group of answer choices: A)True OR > 2.00 (e.g. OR = 2.85) B)True OR < 2.00 (e.g. OR = 1.40)
Determine whether the study is an experiment or an observational study, and then identify a major problem with the study. A sociologist has created a brief survey to be given to 2000 adults randomly selected from the U.S. population. Here are her first two questions: (1) Have you ever been the victim of a felony crime? (2) Have you ever been convicted of a felony? This is an V because the researcher V the individuals. What is a major problem with the study? O A. There is no blinding or replication, which has a high chance of leading to bias. O B. The responses will be voluntary, which will lead to a high chance of bias. O C. Individuals convicted of a felony are more likely to not answer the second question honestly. O D. The sample includes only U.S. adults.
Suppose you are the manager of two beachfront hotels : The Palms and Golden Sands. You'd like to know if there is a difference in guest satisfaction between the two hotels. To investigate this, you conduct a survey and ask guests upon departure if they are likely to return to the hotel in the future. For The Palms, 163 out of 227 guests who were surveyed responded " yes ". For Golden Sands, 154 out of 262 guests responded "yes ". Answer the following questions. Round any numbers in your final answers to 2 decimals. 1) Calculate a 95 % confidence interval for the difference in satisfaction rates between The Palms and Golden Sands (Show work) 2) Use the critical value approach to test, at a 1% significance level, whether or not the guest satisfaction rates are different between the two hotels. What do you conclude ? (In your answer, show the steps involved with testing) 3) What is the p-value of your test in part 2?
A geography test was given to a simple random sample of 500 high-school students in a certain large school district. One question involved an outline map of Europe, with the countries identified only by number. The students were asked to pick out Great Britain and France. As it turned out, 65.6% could find France, compared to 70.4% for Great Britain. Select all statements below that are true. a. Students are different in recognizing France versus Great Britain, and this difference is statistically significant. b. The z-test is not valid because there is dependence between observations in France and Great Britain groups. c. Each ticket in the box model corresponds to a student and has two values, one for the ability to pick France and another for Great Britain. The values can be 0 or 1. d. This is an example of randomized treatment-control experiment.
Reports have found that many U.S. adults would rather live in a different type of community than where they are living. A national survey of 2260 adults asked: "Where do you live now?", and "What do you consider to be the ideal community?" Response options were City (C), Suburb (S), Small Town (T), or Rural (R). A representative portion of this survey for a sample of 100 respondents is as follows: Question 1: Where do you live now?

Hi! I need help with questions one and two. What would I do/how? A popular uprising that started on January 25, 2011, in Egypt led to the 2011 Egyptian Revolution. Polls show that about 70% of American adults followed the news about the political crisis and demonstrations in Egypt closely during the first couple weeks following the start of the uprising. Among a random sample of 60 high school students, it was found that only 34 of them followed the news about Egypt closely during this time. 1. Describe how to perform one repetition of a simulation of the proportion of high school students who followed the Egyptian Revolution using blue and yellow poker chips and, once you had results, how to estimate the p-value. 2. Below is a histogram showing the distribution of the simulated proportions in 1000 simulations under the null hypothesis. Which of the following values is the best estimate for the p-value? A. 0.01 B. 0.04 C. 0.12 D. 0.25
Dr. Moo conducted a research project in which she compared the impact of two types of therapy (pizza therapy and chocolate therapy) and gender on college students’ happiness. How many null hypotheses did she have, and how would you write them?
