The mean marks and standard deviations of students in two subjects are given below:
Subject A: Mean = 36, Standard Deviation = 11
Subject B: Mean = 85, Standard Deviation = 8
Coefficient of correlation between A and B = ±0.66
Determine the two equations of regression and calculate the expected marks in Subject A corresponding to 75 marks obtained in Subject B.
The following data show the age groups of students and the number of regular players in each group:
Age Groups: 15—16, 16—17, 17—18, 18—19, 19—20, 20—21
Number of Students: 200, 270, 340, 360, 400, 300
Number of Regular Players: 150, 152, 170, 180, 180, 120
Apply Chi-Square Statistic and determine whether there is any relationship between age and playing habits of students. Interpret the result clearly.
