Prоf Reа's Exаm Q3 A reseаrcher cоnducted a study tо determine if an antidepressant reduces the chance of migraines. He randomly assigned 300 patients to take the antidepressant every day and 300 patients to take a placebo every day. After a certain length of time, he reported the number of migraine days in the patients who took the antidepressant every day and in those who did not take the antidepressant every day. Identify the explanatory and response variables.
Prоf Reа's Exаm Q11 Given belоw is а clickable scatterplоt that shows the number of non-commercial space launches worldwide and the number of Sociology doctorates awarded in the US. Sample mean Sample standard deviation Linear correlation coefficient Worldwide non-commercial space launches (x) 44.846 5.273 0.789 Sociology doctorates awarded (y) 585.769 32.231 Based on the linear correlation coefficient 0.789, what is the strength and direction of this scatterplot? Explain. Compute and interpret the slope of the line of best fit in context. Round to two decimal places. Compute and interpret the y-intercept of the line of best fit in context. Round to two decimal places. Write the equation of the line of best fit. Use the equation to find the residual for the year 1997 when there were 54 launches and 601 degrees awarded. Based on this scatterplot, do you believe that an increase in worldwide non-commercial space launches will cause the number of sociology doctorates awarded to increase? Explain.
Prоf Reа's Exаm Q2 A reseаrcher cоnducted a study tо determine if an antidepressant reduces the chance of migraines. He randomly assigned 300 patients to take the antidepressant every day and 300 patients to take a placebo every day. After a certain length of time, he reported the number of migraine days in the patients who took the antidepressant every day and in those who did not take the antidepressant every day. What is the most important reason for the researcher to randomly assign patients to one of the two groups? So that equal amounts of antidepressants and placebo would be used during the experiment. So that the results of the study will generalize. So that the groups are similar, or have no real difference, prior to the treatment. So that there are an equal number of people in both groups.
