Cоncerned аbоut declining stаndаrds in the Madisоn school district, a statistician examines the associations between reading proficiency of 11th graders in the district and the graduation rates of those students the following year. The statistician finds that there is a negative correlation of -.768, indicating that as the percentage of students reading at grade level has decreased there has been an increase in the percentage of students graduating with a high school degree. Using the information provided, calculate the line of best fit and then using that formula determine the graduation rate for a cohort of 11th grade students where we now have 45% of the students reading at grade level.   11th Grade Reading Proficiency Graduation Rate Mean 39.33 83.39 SD 6.39 2.78
