An und Tuate student performed a visual experiment on a number of participants. Since the experiment involved displays of colored letters and backgro after the experiment the student wondered whether the presence or absence of color vision in the participants could have produced some of the effects seen in the data. The student went back, tested his participants for colorblindness, and reanalyzed the data. He considered the variables color vision of participant ("colorblind" or "not colorblind") and trial outcome ("hit", "miss", "false alarm", or "correct rejection"). The contingency table below gives a summary of the data from 2000 trials of the experiment. Each of the trials was performed either by a colorblind participant or a non-colorblind participant. Each cell of the table contains three numbers: the first number is the observed cell frequency (f); the second number is the expected cell frequency (f) under the assumption that there is no dependence between the two variables…
Salma publishes a blog on bird-watching, with field notes and pictures of her trips around the country. Recently she decided to conduct a poll among 400 of her subscribers, and found that 68% of those polled have liked at least one of her blogs, they have posted an average of 3.1 comments per blog, and 149 have liked all of her blogs. Later she found out that her website already has this information for all of her subscribers. According to her website, she has a total of 10,985 subscribers, of whom 75% have liked at least one of her blogs, they have posted an average of 2.4 comments per blog, and 4135 have liked all of her blogs. (a) For Salma's blog poll, identify the population and the sample. Population: All the subscribers to Salma's blog Sample: The 400 subscribers Salma polled (b) Choose whether each number described below is a parameter or a statistic for Salma's blog poll.

Helena gathers data about the music preferences of users of a social media application. She gathers information on music events (MEs). In her study, a music event is defined as a posting that has a hashtag or is linked to other video- sharing websites. 1. From her data, Helena claims that about 15% of MEs on the application are hip hop/rap. Juan wants more proof of her claim. • Juan uses technology to determine the genres of music of 100 MEs he chooses at random. He determines that 9 were hip hop/rap. • Juan points out the 9% rate to Helena. Part A Assume Helena is correct and 15% of MEs on the app are hip hop/rap. Use random numbers and a simulated sampling distribution to simulate the outcome of several trials, in which each trial samples 100 MEs from the app and counts the number of hip hop/rap MEs. Make a histogram for your data. Is the model consistent with what you would expect? Explain.
A global research study found that the majority of today's working women would prefer a better work-life balance to an increased salary. One of the most important contributors to work-life balance identified by the survey was "flexibility," with 41% of women saying that having a flexible work schedule is either very important or extremely important to their career success. Suppose you select a sample of 100 working women. d.) If a sample of 400 is taken how does this change your answer to b? The probability that in the sample between 37% and 47%say that having a flexible work schedule is either very important or extremely important to their career success is____.
Imagine I wanted to study the effectiveness of the Mediterranean diet on people’s memory. I tested a group of people who strictly followed the Mediterranean diet, another group who followed a typical Western diet, and another whose diet I did not change at all. Before the diet changes began, I gave all my participants a memory test. After six weeks of the diet experiment, I had all participants complete the same memory test again to see how scores would change among the three groups. For this study, identify a parameter and a statistic I might be interested in.
A popular uprising that started on January 25, 2011 in Egypt led to the 2011 Egyptian Revolution. Polls show that about 70% of American adults followed the news about the political crisis and demonstrations in Egypt closely during the first couple weeks following the start of the uprising. Among a random sample of 60 high school students, it was found that only 34 of them followed the news about Egypt closely during this time. Describe how to perform one repetition of a simulation of the proportion of high school students who followed the Egyptian Revolution using blue and yellow poker chips and, once you had results, how to estimate the p-value.
A researcher conducts an experiment to test whether memory changes with age. They recruited 24 participants separated into four age groups. The groups differ according to the age of subjects. In group one, all participants are 30 years old. Group 2, 40 years old. Group 3, 50 years old. And group 4, 60 years old. Assume that the participants are all in good health and that the groups are matched on other important variables such as years of education, IQ, gender, motivation, and so on. Each participant is shown a series of nonsense syllables ( a meaningless combination of three letters such as Daf or FUM ) at a rate of one syllable every four seconds. The series is shown twice, after which participants are asked to write down as many of the syllables as they can remember. Below is number of syllables remembered by each participant. 30 years old 14 13 15 17 12 10 40 years old 12 15 16 11 12 18 50 years old 17 14 14 9 13 15 60 years old 13 10 7 8 6 9 what is the alternative and null…
A student researcher was surprised to learn that the 2017 NCAA Student-Athlete Substance Use Survey supported that college athletes make healthier decisions in many areas than their peers in the general student body. He collected data of his own, focusing exclusively on male student-athletes to see if such habits vary based on one’s sport. He asked 93 male student-athletes whether they had engaged in binge-drinking in the last month (> 5 drinks in a single sitting). Data are provided in the table below. Lacrosse Hockey Swimming Row Totals Yes – Binge 20 17 15 52 No – did not binge 16 15 10 41 Column totals 36 32 25 93 1. Calculate the effect size.

A national study found that treating people appropriately for high blood pressure reduced their overall mortality by 20%. Treating people adequately for hypertension has been diffcult because it is estimated that 50% of hypertensives do not know they have high blood pressure, 50% of those who do know are inadequately treated by their physicians, and 50% who are appropriately treated fail to follow this treatment by taking the right number of pills. Answer the following questions ( please answer all the parts 1,2 and 3): 1) What is the probability that among 10 true hypertensives at least 50% are being treated appropriately and are complying with this treatment?2) What is the probability that at least 7 of the 10 hypertensives know they have high blood pressure? 3) If the preceding 50% rates were each reduced to 40% by a massive education program, then what effect would this change have on the overall mortality rate among true hypertensives; that is, would the mortality rate decrease…
A poll in June 2020 found that 83% of American parents believe that virtual learning instead of in- person learning widens the equity gap for students. A later poll in October 2020 asked 1025 American parents if they believe virtual learning instead of in- person learning widens the equity gap for students, and found that 820 believe that yes, virtual learning instead of in-person learning widens the equity gap for students. Does this mean that the proportion of American parents, who believe that virtual learning instead of in-person learning widens the equity gap for students, has decreased? Test at the 10% significance level. State the hypotheses. Но: р (? На: р (? Calculate the sample proportion. Round to four decimal places. Calculate the test statistic. Round to two decimal places.

You are interested in testing if there is a difference in weight-loss between 3 popular diet types; low calorie, low fat and low carb. Participants are randomly assigned one of the three groups or a control group. The control group will be told that are participating in a weight-loss study, but will not be following any particular diet. This is to study the placebo effect, weight-loss from just participating in the study. At the start of the study, each participant's weight is recorded in pounds. After 8 weeks they are weighed again, and the weight difference is recorded. A positive value represents a weight loss while a negative value represents a weight gain. Test at 5% significance. Round answers to 3 decimal places. Diet Type Low Calorie Low Calorie Low Calorie Low Calorie Low Calorie Low Fat Low Fat Low Fat Low Fat Low Fat Low Carb Low Carb Low Carb Low Carb Low Carb Control Control Control Control Control Pounds Lost 6.9 4.7 3.5 7.7 5.9 3.8 1.4 3.8 5.2 2 4.9 2.6 2.7 5.6 3.4 1.3…
