In a survey, 1000 individuals were asked how often they took exercise in the form of cycling.There were three possible responses, namely 'never', 'occasionally' and 'frequently'. A similarquestion was asked with respect to walking, with the same three possible responses.Of the 1000 individuals, 75 said that they frequently walked and cycled, 10 never walked butcycled frequently, 35 never cycled but walked frequently, and 100 never walked and nevercycled. In all, 200 individuals never cycled and 125 never walked, whereas 700 cycledoccasionally and 150 walked frequently.(a) Arrange the data in the form of a (3x3) contingency table, and state how many of the1000 individuals both cycle and walk occasionally.(b) Apply a x² test to the (3×3) table, stating clearly the hypothesis which it is designed totest.

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
In 1974, Loftus and Palmer conducted a classic study demonstrating how the language used to ask a question can influence eyewitness memory. In the study, college students watched a film of an automobile accident and then were asked questions about what they saw. One group was asked, “About how fast were the cars going when they smashed into each other?” Another group was asked the same question except the verb was changed to “hit” instead of “smashed into.” The “smashed into” the group reported significantly higher estimates of speed than the “hit” group. Suppose a researcher repeats this study with a sample of today’s college students and obtains the following results. Estimated SpeedSmashed Into Hitn = 16 n = 16M = 40.8 M = 34.0SS = 510 SS = 414 For this problem, complete the four stages of hypothesis testing to determine whether the assumption of homogeneity of variance is met.

The two-way table below reflects the responses from a group of middle and high school students regarding cell phones. What is the best interpretation of the number "25" in the table? would It be There are 25 people have a cell phone 25% of the people are 10 to 12 year old's Out of all 170 people surveyed, only 25 have a cell phone or There are 25 ten to twelve year old's that have a cell phone
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
Inspired by the example about how background music influences choice of entrée at a restaurant, a statistics student decided to investigate other ways to influence a person's behavior. Using 60 volunteers, she randomly assigned 20 volunteers to get a "red" survey, 20 volunteers to get a "blue" survey, and 20 volunteers to get a control survey. The first three questions on each survey were the same, but the fourth and fifth questions were different. For example, the fourth question on the "red" survey was "When you think of the color red, what do you think about?" On the blue survey, the question replaced red with blue. On the control survey, the last two questions were not about color. As a reward, each volunteer was allowed to choose a chocolate candy in a red wrapper or a chocolate candy in a blue wrapper. The table shows the result of the experiment. We want to test Ho: The distribution of candy choice is the same for subjects like these who receive the red survey, the blue survey,…
According to Inc.com, 71% of job seekers used social media in their job search in 2018. Many believe this number is inflated by the proportion of 22- to 30-year-old job seekers who use social media in their job search. A survey of 22- to 30 -year-old job seekers showed that 310 of the 370 respondents use social media in their job search. In addition, 275 of the 370 respondents indicated they have electronically submitted a resume to an employer.
There are 9 million enrollees in the Department of Veterans Affairs health care system. It wants doctors and nurses to treat pain as a “fifth vital sign” to be recorded along with blood pressure, pulse, temperature, and breathing rate. If you were to aid the VA in this situation, how would you measure a patient’s pain? How could this “fifth vital sign” be a potentially invalid measure? Answer each question with at least one paragraph of three complete sentences.
Sophomore, junior, and senior students at a high school will be surveyed regarding a potential increase in the extracurricular student activities fee. There are three possible responses to the survey question - agree with the increase, do not agree with the increase, or no opinion. A chi-square test will be conducted to determine whether the response to this question is independent of the class in which the student is a member. How many degrees of freedom should the chi-square test have?
A group of 91 students were surveyed about the courses they were taking at their college with the following results:39 students said they were taking Math.47 students said they were taking English.38 students said they were taking History.14 students said they were taking Math and English.16 students said they were taking Math and History.27 students said they were taking English and History.11 students said they were taking all three courses.How many students took none of the courses ?
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…
Assume that 135 surveys are completed. Of those surveyed, 61 responded positively to effectiveness, 65 responded positively to side effects, and 63 responded positively to cost. Also, 26 responded positively to both effectiveness and side effects, 29 to effectiveness and cost, 26 to side effects and cost, and 16 to none of the items. How many responded positively to all three?
