- The Higher Education Research Institute at UCLA collected data from 203,967 incoming first-time, full-time freshmen from 270 four-year colleges and universities in the U.S. 71.8% of those students replied that, yes, they believe that same-sex couples should have the right to legal marital status. Suppose that you randomly pick seven first-time, full-time freshmen from the survey. You are interested in the number that believes that same-sex couples should have the right to legal marital status.What is the probability that at least two of the freshmen reply "yes"?

- A group of 1440 students was surveyed in October 2018 about their sleeping patterns and consumption of caffeinated beverages. Of the 1440 students asked, 834 said they had trouble falling asleep at night, but the rest did not. Of the 834 who said they had trouble sleeping at night, 640 drank some type of caffeinated beverage after 2 pm most days. Of those who reported no trouble falling asleep at night, 108 said they drank some type of caffeinated beverage after 2 pm most days.Some government officials are proposing for the country’s academic calendar to be moved from June-March to August-May. This proposal, according to the officials, if approved, can further improve education by synchronizing our calendar with that of the other countries. Government officials would push through with the proposal if at least 85% of the student population favor it. To know the opinion of learners regarding the said proposal, a simple random sample of learners was obtained and they were asked if they were in favor of the said proposal. Of the 1,000 surveyed learners, 892 said they were in favor of the approval of the said proposal. a.Find a point estimate of the true proportion of learners who are in favor of the approval of the proposal and find its standard error.If you have a study in which 40 participants are randomly assigned to one of the four groups, the dfbetween =

- b) A certain pay television company wishes to estimate the proportion of its customers who would purchase a pay television program guide. To do this, the company manager decides to select a random sample of customers and note the number who would purchase a program guide. Suppose that experience in other areas suggests that about 13% of customers will purchase a program guide. How many customers should the company manager include in his sample if he wishes to estimate the true proportion who will purchase the program guide correct to within 5% (0.05) with a confidence level of 95%?It is known that 9 out of 10 people are right handed.

Show your work below.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). What do the researchers mean by "Amazon's Mechanical Turk" with respect to their sample of participants? O A. An archival data set that already exists and from which researchers can use data O B. An online tool that researchers can use to recruit people to participate in research in exchange for a small payment O C. An e-book sold by Amazon that includes contact information for possible…
