You will note that the assignment for this week is similar to the multiple regression analyses you did in the Quantitative Reasoning and Analysis course in weeks 9 and 10. When you conduct your multiple regression analysis for this assignment you should not turn in a paper you submitted in an earlier course or use the same variables that you used to conduct a multiple regression. Please note that SafeAssign will match your assignment to your submission(s) from the earlier course and it is not permissible to reuse work from previous courses without specific permission from your instructor.For this assignment use different variables than you did for previous multiple regression assignments.To prepare for this AssignmentReview this week’s Learning Resources and media program related to multiple regression.Based on the dataset you chose, construct a research question that can be answered with a multiple regression analysis.Write a 1- to 2-page analysis of your multiple regression results for each research question. In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.Use proper APA format, citations, and referencing for your analysis, research question, and display of output.ReferencesFrankfort-Nachmias, C., & Leon-Guerrero, A.

A rehabilitation center researcher was interested in examining the relationship between physical fitness prior to surgery of persons undergoing corrective knee surgery and time required in physical therapy until successful rehabilitation. Patient records in the rehabilitation center were examined, and 24 male subjects ranging in age from 18 to 30 years who had undergone similar corrective knee surgery during the past year were selected for the study. The number of days required for successful completion of physical therapy and the prior physical fitness status (below average, average, above average) for each patient follow.(1) Using SAS to test whether the mean number of days for successful completion of physical therapy differ significantly among the three groups. (clarify your notation, specify hypothesis, test statistics, rejection region or p-value, and your conclusion).(2) Write down your fitted model. What do the estimated coefficients represent? (Hint: beta0 is mean of reference group, etc.)Note: Group 1 has 8 individuals, group 2 has 10 and group 3 has 6 individuals. To read in the data, you’ll need to organize the data in the format like EX1701.DAT (or page 5 of slides “onewayANOVA-2020.ppt”) as following :Group daysBA 29BA 42BA 38…AV 30AV 35…
