Identify the independent (or quasi-independent) and dependent variables in the following examples. Also have identify the type of manipulation used for the independent variable and the scales of measurement for the dependent variable(s). Discuss each example and consider any confounding variables that may pose a problem for the study. Researchers design a study to measure responses of subway passengers to information announced over the intercom. The same announcement will be made by the conductor, but in one condition, a bell noise will precede the announcement. At the next stop, passengers will be interviewed to determine whether they heard they announcement and if they could decipher the message.
Which of the independent variables retains the strongest association with the number of children a respondent has when all other variables in the model are controlled?
You may need to use the appropriate technology to answer this question. An automobile dealer conducted a test to determine if the time in minutes needed to complete a minor engine tune-up depends on whether a computerized engine analyzer or an electronic analyzer is used.

Answer: A professor wishes to study the daily recoveries from COVID-19 during four consecutive days in two countries, UG and OM. Data for Country UG = {3,8, 10, 6} and Country OM = {8,9, 10, 6} were of collected. Which country had more variable COVID-19 recoveries? Select one: O a. Country with more variations in recoveries from COVID-19 is UG. O b. Both countries UG and OM have same variations in recoveries from COVID-19. OC. Country with more variations in recoveries from COVID-19 is OM. O d. It is not possible to determine which country had more variations in recoveries from COVID-19.
MR In Dave Eggers’ novel The Circle, a mysteri-ous technology company has developed a strangely data-driven work environment in which employees are assigned a performance score that seems to be the product of factors in their social activities and environment, such as the extent of their engagement in work community and the number of times they post on the company’s social media site. Using the fictional data below, compute r and r2 for each com-bination of two variables from this novel and test the correlations for their significance. Write a paragraph interpreting the relationships between these vari-ables, and what they might mean for the company
