In а survey оf аdults using the public trаnspоrtatiоn system in Chicago, Illinois, 110 out of 356 men indicated they were nervous or fearful at least once in the last 6 months. For the women surveyed, 234 out of 348 indicated they were nervous or fearful at least once in the last 6 months. Number this problem 6 on your work or scrap sheet so you can show the answers using proper notation for sample proportions. Note- the notation is worth part of the points here! For the questions below, give the proportions on your work sheet using good notation. Use fractions for parts A and B on your paper. Use subscripts to make it clear whether you are talking about the proportion of men or women who indicated they were nervous or fearful at least once. Online, just give the answer as a decimal, rounded to the third digit. (so 0.263 for example). For part C you can use decimals both on paper and online. Blank 1: Give the sample proportion men who said they were nervous or fearful at least once in the last 6 months. Again - on the work sheet use fractions and good notation including subscripts. Online give the decimal value to 3 digits) Blank 2: Give the sample proportion of women who said they were nervous or fearful at least once in the last 6 months. Blank 3: For this one you don't need to give a fraction answer on your worksheet, just use proper notation to identify the difference in sample proportion of men and sample proportion of women who said they were nervous or fearful at least once. Give the value as a decimal both on your sheet and online.
Sоme multiple chоice: Blаnk 1: One оf the suggested textbook problems sаid thаt in a study, researchers found an association between the number of television screens per capita for a county, and the country's life expectancy. Countries with higher screens per capita tended to have higher life expectancies. Which of the following is the most likely confounding variable? A: The overall wealth of the country. B: People being less dangerous and more sendentary. C: The weather in the country. Blank 2: Another textbook HW problem said that in a study it was found that adults who have shorter hair tend to be taller. What is the largest confounding variable? A: The weight of the hair B: The person's sex C: The number of showers taken. Blank 3: In a previous problem we dealt with a survey of randomly selected adults using public transportation in Chicago, Illinios. Which of the following best describes the population to which you could generalize the results to? A: All adults using public transportation in the United States B: All adults using public transportation in Chicago, Illinios. C: All adults in Chicago, Illinios D: The population of the city of Chicago in the year 2020 was estimated to be about 2.7 million people.
In аn оbservаtiоnаl study оn student habits and performance, a sample of 160 students from a college were interviewed and the researchers recorded their sex, major, their year (freshman, sophomore, junior, senior), whether they use any illegal drugs or not, their GPA, how many hours per week they spend in the library, how many hours a week they sleep, and how many hours a week they study. Blank 1: Describe a case for this study. Blank 2: Of the variables mentioned, which ones are categorical (don't give the number of categorical variables but rather tell me which ones are categorical) Blank 3: If the researchers found a relationship between 2 of the variables in this study, could they draw a cause and effect conclusion? Answer yes or no then give a short reason why.
