A sociologist is interested in studying the impact of belonging to a Greek fraternity or sorority on college graduation rates. Research assistants queried university records to identify 250 students, who had first enrolled five years prior. Of the 250 students, 125 had pledged a Greek organization and 125 had not. They determined that 115 of the students had graduated. Thus, for the graduation rate, the size of the sample space was Assuming a uniform probability model for these 115 successful graduates, the theoretical probability of having been in a Greek organization should be However, when the actual data was examined, the study found that of the successful graduates had been fraternity or sorority members , while only 40 graduates were not affiliated. Thus, the experimental probability of a graduate belonging to a Greek organization was which was the expected theoretical probability

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
