- In 2013 students from a Statistics class at FSEV UK were asked to survey their friends who were 15-30 years old, in order to explore the interests of young people. The survey has a variety of questions, which are detailed in the Survey Key. For example, the column header “Music” is short for the question “I enjoy listening to music” and is rated 1-5, where 1 represents strongly disagree and 5 represents strongly agree. There is also some categorical data present as well. Survey participants record their gender, how often they smoke/drink, their internet usage, and education (just to name a few!). Please perform a hypothesis test based on one of the categorical variables and one survey question. For example, you could choose to prove the following: Survey participants who identify as an “only child” enjoy meeting new people (Survey score ). Here is an example: people who are right-handed (as identified in the data set) enjoy listening to music. Please be sure to use two columns…Compute the mean, median, and mode of the data sample. (If every number of the set is a solution, enter EVERY in the answer box.) 3, 1, 7, −4, 0, 5 mean median modewhat kind of statistical data might a barglar alarm company employ in trying to convince urdban homeowers to purchase its products

- A researcher wants to compare the effectiveness of three different teaching methods (A, B, and C) on exam scores. The researcher gathers exam scores from 20 students for each teaching method, and wants to determine if there is a significant difference in the mean exam scores between the three teaching methods. What test can the researcher use to answer this question?2. Report the statistical results for a three sets of data in APA style.The American Water Works Association reports that, The average household water usage is more than 10 gallons per day. However, in a pandemic like this, it is suspected that there is a change in household water consumption. A researcher conducted a survey and took samples of 12 household heads and asked about the use of the gallon water. The data obtained are as follows: 74, 8, 13, 17, 13, 15, 12, 13, 15, 16, 9, 7. If it is known that the data is normally distributed. Use a significance level of 5% to test whether the average household water use has increased (greater than 10 gallons)? What will happen if the household's water use increases by 5% from the previous one? Analyze your answer and come up with a conclusion!
- The Following are Data for Systolic Blood Pressures, in mm of Mercury, of 12 Chimpanzees. 121, 125, 128, 134, 136, 138, 139, 141,144, 145, 149, 151 Based on this sample, do chimps have higher systolic blood pressure than humans, their closest relatives? Make sure you state the statistical hypotheses and conclusions, as well as the biological conclusions.The best measure of central tendency for systolic blood pressure readings obtained from a population of 7 individuals whose systolic blood pressure readings were 101, 104, 108, 109, 111, 112, and 160 is the mean. Is it?An interviewer stops people on the street to do a survey concerning illegal drug use. How can this give bias data and how can it be more reliably collected?
