5. A reason people give for drinking coffee is "alertness" or "energy". This could be the case for kids who drink coffee. Or they could be groggier from a lack of sleep due to coffee. We asked ni=50 17-year-old kids who drink coffee if they "felt alert" X1=30 answered yes, we then asked n2-50 kids who don't drink coffee and x2-20 of the kids answered that they the "felt alert". We would like to compare these two proportions. a. What are the estimated proportions? b. What are the null and alternative hypothesis? C. Perform the test, what do you conclude?

The college newspaper of a large Midwestern university periodically conducts a survey of students on campus to determine the attitude on campus concerning issues of interest. Pictures of the students interviewed along with quotes of their responses are printed in the paper. Students are interviewed by a reporter "roaming" the campus selecting students to interview "haphazardly." On a particular day, the reporter interviews five students and asks them if they feel there is adequate student parking on campus. Four of the students say, "no." Which of the following conditions for inference about a proportion using a confidence interval are violated in this example? 1. The data are an SRS from the population of interest. II. The population is at least ten times as large aş the sample. III. np > 10 and n(1 – p) > 10 O All three conditions are violated O Il only O l and III O Il only O I only

A report describes a survey of 251 adult Americans. Participants in the survey were asked how often they disinfect their phone and were asked to respond with one of the following categories: more than once a week, once a week, every other, week, every three weeks, or less often than every three weeks. For this group, 9% responded more than once a week, 52% responded once a week, 26% responded every other week, 6% responded every three weeks, and 7% responded less often than every three weeks. Fill in the table below with the relative frequency distributions. How Often? Relative Frequency More than once a week Once a week Every other week Every three weeks Less often than every three weeks
24) Some research has shown that swearing can help reduce ratings of pain (Stephens, Atkins, & Kingston, 2009). In one such study, each participant was asked to plunge a hand into icy water and keep it there as long as the pain would allow. In one condition, the participants repeated their favorite curse words while their hands were in the water. In the other condition, the participants repeated a neutral word. In addition to lowering the participants’ perception of pain, swearing also increased the amount of time they were able to tolerate the pain. Data similar to the results obtained in their study are shown in the following table. Amount of Time (in Seconds) Participant Swear Words Neutral Words 1 94 59 2 70 61 3 52 47 4 83 60 5 46 35 6 117 92 7 69 53 8 39 30 9 51 56 10 73 61 Do these data indicate a significant difference in pain tolerance between the two conditions?…
Does grade level matter regarding having a drink of coffee before going to school? To get some insight relating to this question, Professor Jay randomly selected nm = 1142 New York City high school freshmen. Of these, xm = 803 said they had at least one cup of coffee before going to school. Professor Jay also randomly selected nf = 1012 New York City high school seniors. Of these, xf = 760 said they had at least one cup of coffee before going to school. Suppose Pm is the true proportion of New York City high school freshmen who have a drink of coffee before going to school. Suppose pf is the true proportion of New York City high school seniors who have a drink of coffee before going to school. Pm and pf are unknown and we will examine relations between them based upon Professor Jay's samples. Let pmhat be the sample proportion of high school freshmen who said they had at least one cup of coffee before going to school. Let pfhat be the sample proportion of high school seniors who said…
Moral judgments about a harmful behavior are expected to be associated with one’s ability to recognize how hurt the victim of the harmful behavior is. To test this a replication of the Malti and colleagues (2012) was attempted. Researchers asked 12- and 15-year-olds whether they thought it was okay to exclude a Serbian peer from going to a soccer match (1 = really not okay, 7 = really okay) and how they thought the Serbian peer would feel if he/she was not invited to the soccer match (1= very bad, 7 = very good). The results for 12 of these adolescents are below: 1. Find the correlation, r, between exclusion judgments and evaluations of the victim’s feelings (assuming the researcher wanted to use the 1 to 7 scale as a numerical interval score). Q: r= ? 2. Describe this correlation and what does this correlation indicate about the relation between exclusion judgments and evaluations of the victim’s feelings?

A high school track coach wanted to test whether giving the students an energy drink could affect performance during the 100 meter race. The coach split the 26 boys into two equal sized groups, where Group 1 was given the energy drink and Group 2 was not. The 100 meter race times were recorded during practice and shown in the table below. What inference can be made about the results? Group 1 Group 2 12.2 13 12.5 12.3 13.3 12.8 12.9 13 13 13.8 12.1 13 13 13 13 13 12.1 13 13 13 12.1 13 12.8 13 13 12.6 Mean: 12.7 Mean: 13 Since the simulation shows ( many cases or free cases )? where a mean difference of ( solve for this answer ) or less occurred when the groups were re-randomized, it can be inferred that the mean difference observed in the study was ( very possibly or very unlikely ) ?due to the random assignment of participants into groups, so the results of the study are (…
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…
A radio station surveyed 110 students to determine the sports they liked. They found 45 liked basketball, 70 liked football, and 35 liked neither type. Let U = {all students surveyed}, B = {students who liked basketball}, F = {students who liked football}. How many of the students liked at least one of the two sports? n(BnF)
