Researchers investigated whether the type of music playing in a waiting area affected people's shyness. Stu-dents from a sample of N = 15 were randomly assigned to one of three music conditions (silence, pop, orfunky jazz). Each student was led into a room where the music was playing and asked to sit and wait for theexperimenter to call them in. There was a row of 12 chairs in the room and a confederate of the experimenter,pretending to be another participant, was already seated in the first chair. The experimenter noted how manyseats away from the confederate the participant choose to sit.Here are the data from students in the silence condition: 3, 5, 5, 7, 6, 5.Here are the data from students in the pop condition: 4, 6, 7, 6, 6.Here are the data from students in the funky jazz condition: 5, 3, 3, 3.Calculate the average distance that the participants sat from the confederate in each music condition, anddetermine whether the type of music had a significant effect on how far away the participants sat from theconfederate, and calculate the effect size: 2. Report the results of your analyses in a sentence or two that issuitable for the Results section of an APA-style research article.

A researcher studies the effects of guilt on memory. First, subjects perform a very boring task for one hour. Then each subject is instructed to tell the next subject either (a) that the experiment took one hour and they found it very boring, or (b) that the experiment took one hour and was very interesting. After that, each subject is asked to study a list of words and are tested on memory for the list. 30 subjects are randomly assigned to one of the two conditions. In order to see whether the experimental manipulation has any effect on memory, which would be the proper statistical test? A)a related sample t-test-test   B)an independent sample t-test   C)a z test   D)a one sample t

Can an interviewer influence how people respond to the survey question, "Do you like dogs?" To answer this question, Jason carried out an experiment. As each person approached, Jason flipped a coin. If it landed on heads, Jason picked up his puppy and asked the person if they like dogs. If the coin landed on tails, Jason picked up a clipboard and asked the person if they like dogs. Of the 50 people that Jason surveyed while holding his puppy, 35 said "Yes," while 11 of the 44 people that Jason surveyed while holding his clipboard said "Yes." Let p₁ = the true proportion of people like the ones in this study who would say they like dogs when Jason is holding his puppy and p2 = the true proportion of people like the ones in this study who would say they like dogs when Jason is holding a clipboard. Construct and interpret a 90% confidence interval for the difference in the proportion of people like these who would say they like dogs when Jason is holding his puppy or a clipboard. O…
The P&G marketing team has created two potential slogans for the new Smile toothpaste. The uplifting slogan is, “Smile when you buy Smile!”. The serious slogan is, “Buy Smile to keep your smile.” Before deciding which slogan to use, the marketing team runs an experiment to see how individuals respond to these two slogans. The marketing team recruits 46 people to participate in this experiment, randomly assigning 24 participants to read the uplifting slogan and 22 participants to read the serious slogan. After reading the slogans, all participants rate how likely they are to buy the new Smile toothpaste on a scale from 1 (definitely will NOT purchase) to 10 (definitely will purchase). The group of participants who read the uplifting slogan has a mean score of 6.67, with a sum of squares of 323. The group of participants who read the serious slogan has a mean score of 4.77, with a sum of squares of 221. Do participants who read the uplifting slogan versus the serious slogan differ…
In a survey, it was found that 80% of adults operate the flusher of toilets in public restrooms with their foot. (a) If 300 adults are randomly selected, how many would we expect to flush toilets in public restrooms with their foot? (b) Would it be unusual to observe 270 adults who flush toilets in public restrooms with their foot?
Hypnosis. A sample of 100 people was separated into children and adults. The members of each group were randomly assigned to two different hypnosis exercises. The responses of each person were recorded at the completion of the experiment
In a survey about people's relationship with their pets, one of the questions asked if the person felt guilty when they left their pets alone when they went on holidays. The response for each person was recorded as "Yes- feels guilty" or "No - does not feel guilty". The researchers were interested to see if men and women felt differently in this situation. Which of the following procedure is the most appropriate one to decide if the feeling of being guilty about leaving pets alone is different for men and women: A) Chi-squared test for independence B) Paired T-test C) Unpaired T-test D) Linear regression
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…
A recent study investigated whether cell phone users experience separation anxiety when they cannot access their phones. Because blood pressure increases with anxiety, the researchers used systolic blood pressure as an operational measure of anxiety. The experiment involved a random sample of cell phone users that were divided into two groups at random. One group of participants completed a survey while their phones were locked in a cabinet in a separate room and the other group of participants completed the same survey while their phones were nearby. (The survey questions were unrelated to cell phone use.) At the end of the survey, theresearchers measured each participant's systolic blood pressure. The same experiment was conducted in Montreal, Toronto, Vancouver, and St. Zotique. The blood pressure data for all participants needed are below. Use these data to answer the following question: comoute the estimated standard error of d for the data collected in toronto. Please answer to 5…
A study compares students who use a website and students who do not use the website. In addition to asking the students in the samples about GPA, each student was also asked how many hours he or she spent studying each day. The two samples (141 students who were users of the website and 68 students who were not users of the website) were independently selected from students at a large, public university. Although the samples were not selected at random, they were selected to be representative of the two populations. n USE SALT For the sample of users of the website, the mean number of hours studied per day was 1.46 hours and the standard deviation was 0.83 hours. For the sample of students who do not use the website, the mean was 2.77 hours and the standard deviation was 0.99 hours. Do these sample data provide convincing evidence that the mean time spent studying for users of the website at this university is less than the mean time spent studying by students at the university who do…
The statistics department at a large Midwestern university is interested in how students feel about their introductory statistics course. They decide to randomly select 60 introductory stats students to give a survey, 10 from both the freshman and sophomore class ranks and 20 from both the junior and senior class ranks. They discover that of the 60 total respondents, 73% have a positive attitude toward intro stats. The proportion of the 60 introductory statistics students surveyed by the statistics department that did have positive attitudes toward intro stats (73%) is called a O a. population parameter O b. residual O c. correlation coefficient O d. sample statistic 3 Stat100 Practice..pdf 7 Writing Prompt 3.docx E Online Syllabus J...pdf E Bios357Schedul.pdf SH OCT1 étv 20 F3 トI A FI F9 F10 F5 F7 F8 F2 F4 %23 2$ & * 2 4. 5 6 7 8 9 Q W E T Y S F G H K しの
