- Question Heip People were surveyed worldwide, being asked the question "How important is acquiring wealth to you?" Of 1516 respondents in country A, 1164 said that it was of more than average importance. In country B, of 1325 respondents, 610 said it was of more than average importance. a) What proportion thought acquiring wealth was of more than average importance b) Create a 99% confidence interval for the percentage of people who thought it was of more than average importance in country A. (Be sure to test conditions.) Compare that to a confidence interval for the country B population. each country's sample? a) The sample proportions are 0.768 for country A and 0.460 for country B. (Round to three decimal places as needed.) b) What is the confidence interval for country A? Select the correct choice below and, if necessary, fill in the answer boxes within your choice. O A. The 99% confidence interval for country A is ((76.8 %, 46.0 %) (Round to one decimal place as needed.) O B. The…Scenario: A researcher wants to see whether ESP abilities in psychics differ based on environment. Thus, the researcher has psychics predict card suits in both a fortune-telling environment (e.g., low lighting, candles, a crystal ball), and in a standard lab environment. They complete 100 trials of the task in each environment, with the environment type counterbalanced between participants. All 30 psychics completed the card prediction task in both environments. Accuracy rates are compared. Question: What is the dependent variable in this scenario? Group of answer choices Environment Accuracy rate ESP Card suitBullying,” according to noted expert Dan Olweus, “poisons the educational environment and affects the learning of every child.” Bullying and victimization are evident as early as preschool, with the problem peaking in middle school. Suppose you are interested in the emotional well-being of not only the victims but also bystanders, bullies, and those who bully but who are also victims (bully-victims). You decide to measure anxiety in a group of bullies and a group of victims using an 18-item, 5-point anxiety scale. Assume scores on the anxiety scale are normally distributed and that the variances of the anxiety scores are the same among bullies and victims. The group of 23 bullies scored an average of 40.1 with a sample standard deviation of 10 on the anxiety scale. The group of 28 victims scored an average of 46.8 with a sample standard deviation of 11 on the same scale. You do not have any presupposed assumptions about whether bullies or victims will be more anxious, so you formulate…

- K Do freshmen spend significantly more time on social media than other class ranks? A recent study investigated the amount of time per day freshmen, sophomores, juniors, and seniors spent on social media while doing schoolwork. The students surveyed were U.S. residents from a 4-year, public, primarily residential institution. The accompanying computer output shows the mean time each cohort spent on social media and an ANOVA table.
