Class 10 statistics

In an university, out of 120 students, 15 opted mathematics only, 16 opted statistics only, 9 opted for physics only and 45 opted physics and mathematics, 30 opted physics and statistics, 8 opted mathematics and statistics and 80 opted physics. By drawin Venn diagram, find the number of students who (i) opted mathematics (ii) opted statistics (iii) did not opted any of the above three subjects.

The test marks in statistic for a class are 20,24,27,38,18,42,35,21,44,18,31,36,41,26,29. The median score of the class is

In a class of 125 students 70 passed in Mathematics, 55 in statistics, and 30 in both. Then find the probability that a student selected at random from the class has passed in only one subject.

For 50 students of a class, regression equation of marks in statistics (x) on marks in Accountancy (y) in 3y-5x+180=0 . The mean in Accoutancy is 44 and the variance of marks in statics is 9/16 of the varience of marks in Accountancy. Find the mean marks in Statistics and coefficient of correlation between marks in two subjects.
