A survey of 539 adults aged 18-24 year olds was conducted in which they were asked what they did last Friday night. It found: 162 watched TV 176 ate pizza 26 watched TV and ate pizza, but did not hang out with friends 32 watched TV and hung out with friends, but did not eat pizza 40 hung out with friends and ate pizza, but did not watch TV 29 watched TV, hung out with friends, and ate pizza 74 did not do any of these three activities How may 18-24 year olds (of these three activities) only hung out with friends last Friday night?

2. 2) According to the National Institute on Alcohol Abuse and Alcoholism, 45% of college students nationwide engage in "binge drinking" behavior, having 5 or more drinks in one occasion during the past two weeks. A college president wonders if the proportion of students enrolled at her college that binge drink is actually lower than the national proportion. In a commissioned study, 348 students are selected randomly from a list of all students enrolled at the college. Of these 149 admitted to having engaged in binge drinking. A. State the null and alternative hypotheses. B. State the p-value. C. What is your conclusion about the null hypothesis? Use a 5% level of significance. D. What is your conclusion in context of this problem?
A study was conducted to investigate the effectiveness of hypnotism in reducing pain. Results for 8 randomly selected subjects are shown in the data below.Subject: A, B, C, D, E, F, G, HBefore: 6.6, 6.5, 9.0, 10.3, 11.3, 8.1, 6.3, 11.6After: 6.8, 2.4, 7.4, 8.5, 8.1, 6.1, 3.4, 2.0A lower score indicates less pain. The "before" value is matched toan "after" value and the differences are calculated. The differences have a normal distribution. Are the sensory measurements, on average, lower after hypnotism?Test at a 5% significance level.

Read the study below carefully. Then answer the questions that follow by typing in the letter of the correct response. Rhianna hears that watching ASMR videos on YouTube can help with insomnia. She conducts a sleep study on 60 people who have difficulty sleeping by asking a simple random sample of 30 participants to watch at least 20 minutes of ASMR videos prior to sleeping and the remaining 30 participants to attempt to sleep without watching any videos. During the study, the subjects are connected to an EEG machine, which is used to measure brain activity. Rhianna analyzes the EEG results and concludes that those who watched the ASMR videos experienced a better quality of sleep than those who did not. i. Identify the treatments in Rhianna’s study. A. being connected to an EEG machine B. experiencing difficulty sleeping C. watching at least 20 minutes of ASMR videos D. watching at least 20 minutes of non-ASMR videos E. watching no videos prior to sleep F. all…

It was found that: 137 take math, 50 take history, 124 take English, 33 take math and history, 29 take history and English, 92 take math and English, 18 take math, history and English. From the given information, there are a. Blank 1 students taking neither math nor history. b. Blank 2 students taking at least 2 subjects. c. Blank 3 students taking no more than one subject.
Rachel Green, a fashion buyer at Ralph Lauren, wanted to know which seasonal clothing line Ralph Lauren customers prefer. She randomly selected 200 Ralph Lauren customers to survey about their seasonal preferences. She asked the following question: "Which seasonal clothing line is your favorite: spring, summer, fall, or winter?" The results were as follows: Spring: 10 Summer: 11 Fall: 149 Winter: 20 Based ONLY on this information (do not try to infer anything else!), answer the following questions. Did sampling bias occur? Why or why not? Did response bias occur? Why or why not? Did nonresponse bias occur? Why or why not?
A warehouse manager wants to know if there is an association between the shift worked and being on time for work. To investigate, he selects a random sample of 70 workers and classifies each one according to the shift they worked most recently and whether they were on time for work. He was unable to classify a substantial number of people as being on time, so he classified those individuals as unknown. The data are displayed in the table. The manager would like to know if these data provide convincing evidence of an association between the shift worked and being on time in the large population of all workers at this warehouse. The random and 10% conditions are met. Is the Large Counts condition met? Yes, the smallest expected count is 5, so all expected counts are at least 5. Yes, the smallest expected count is 8.54, so all expected counts are at least 5. No, the smallest expected count is 2.56, so the expected counts are not all at least 5. No, the smallest expected count is…
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

2. A study for adverse reactions assigned adults at random to one of two common pain relievers (ibuprofen and acetaminophen). It was found that out of 733 adults who were administered ibuprofen, 103 of them experienced an adverse reaction, and out of 732 adults who were administered acetaminophen, 85 of them experienced an adverse reaction. Let p1 denote the proportion of adults who experience an adverse reaction when taking ibuprofen and let p2 denote the proportion of adults who experience an adverse reaction when taking acetaminophen. Suppose we want to answer the following questions. i) Test, at the 3% level of significance, whether the proportion of adults who experience an adverse reaction when taking ibuprofen is greater than the proportion of adults who experience an adverse reaction when taking acetaminophen. ii) Calculate the 97% confidence interval for p1 - P2. The table below provides the information needed to perform the hypothesis test: Value x1 103.0000 85.0000 733.0000…

As a destination marketing director, you found that TV executives used the guideline that 25% of the viewers were watching Fox cable network, 22% watching NBC and CBS, and 19% watching ABC. The remaining 12% were watching other cable networks such as CNN and MSNBC on a weekday night. A random sample of 500 viewers in the D.C. metro area last Tuesday night showed 109 homes were tuned in to the Fox station, 125 homes tuning in to NBC affiliate, 100 homes tuning in to CBS affiliate and 81 homes tuning in to ABC affiliate. 85 homes were watching CNN and NSNBC cable stations. At the 0.05 significant level, can we conclude that the guideline is still reasonable?
