Q3 GIVEN THE TREND EQUATION NO OF STUDENTS-3000+200 YEAR BASE: 2003-0 1.INTERPRET EQUATION RESULTS 2.FORECAST FOR 2020 3.WHEN WILL THE NO OF STUDENTS REACH 6000

Solution

x no of years from 2003 y no of students y = 3000+200x 1) The regression equation has a positive slope of 200 y intercept is 3000 i.e. no of students in the year 2000 Thus for every year 200 students increase 2) For 2020, x = 17, y = 3000+200(17) = 6400 3) When y =6000, 6000 = 3000+200x or x = 15 Hence in year 2018 students reach 6000 B Regression C D. All the above
