In a survey of 1000 randomly selected adults in the United States, participants were asked what their most favorite and what their least favorite subject was when they were in school (Associated Press, August 17, 2005). In what might seem like a contradiction, math was chosen more often than any other subject in both categories! Math was chosen by 232 of the 1000 as the favorite subject, and it was also chosen by 366 of the 1000 as the least favorite subject. A USE SALT (a) Construct a 95% confidence interval for the proportion of U.S. adults for whom math was the favorite subject school. (Give the answers to three decimal places.) (b) Construct a 95% confidence interval for the proportion of U.S. adults for whom math was the least favorite subject. (Give the answers to three decimal places.)

In order to conduct an experiment, 4 subjects are randomly selected from a group of 47 subjects. How many different groups of 4 subjects are possible? The number of possible different groups is. (Type a whole number.)
Select the correct response. For a research study, there are five options for the first question, four options for the second question, and three options for the third question. Using a list, there would be outcomes for the sample space. For a similar study, if there are only four options for the first question, the sample space would have outcomes.
g) The Lady Tasting Tea Experiment. An English lady, Muriel Bristol, claimed that she can tell whether tea or milk was added first to a cup. So as a researcher, you want to test whether she can really tell whether tea or milk was added first. But how would you do it? A possible research design: Give her eight cups, four where tea is added first and the other four where milk is added first, in random order. Then ask her to pick out the four cups where the milk is added first. After you conducted the experiment and collected the data, how do you decide whether she can truly tell the difference or she was just guessing. Our intuition tells us that the more cups she gets correctly, the more likely that she is NOT guessing. "If the Lady is just guessing, the probability of getting it all correctly is 1.4%." Now using your knowledge on combinatorics and probability, explain how this number was calculated? h) Suppose you flip four fair coins. What is the probability that you will get all…

Each day the officer visits with students, eats lunch with students, attends pep rallies, and so on.

In a series of studies, Sebastian Deri and his colleagues (2017) asked multiple groups about the number of friend groups they had and how often they attended different social events. They then asked participants how they thought their own numbers compared to other people's: Did participants see themselves as less social, the same as, or more social than others? In the first study, the researchers reported that: "Three hundred four participants from Amazon's Mechanical Turk (150 women; Mage = 37.1; 78% White, 10% Black, and 6% Asian) completed a survey in exchange for modest payment" (p. 860).
