Rs = 0.5 submission of x y is equals to 120 Y is equals to 8 x square ...
Calculation of n using Correlation and Regression



  • Given:


    • Rs = 0.5

    • X + Y = 120

    • Y = 8

    • X^2 = 90

    • X = x - x^2

    • Y = Y - Viber




  • Correlation Coefficient (r):


    • Correlation coefficient (r) is given by:



      • r = (nΣXY - ΣXΣY) / sqrt((nΣX^2 - (ΣX)^2)(nΣY^2 - (ΣY)^2)))



    • Where:


      • n = Number of observations

      • X and Y = Variables

      • ΣXY = Sum of the product of deviations of X and Y from their respective means

      • ΣX and ΣY = Sum of deviations of X and Y from their respective means

      • ΣX^2 and ΣY^2 = Sum of squares of deviations of X and Y from their respective means




    • Substituting the given values, we get:



      • r = (n(8x - x^2) - (8 + x)(120 - x)) / sqrt((n(90 - x^2) - (8 + x)^2)(n(64 - Viber^2) - (8 - Viber)^2)))






  • Regression Equation:


    • The regression equation is given by:



      • Y = a + bX



    • Where:


      • a = Y-intercept

      • b = Regression coefficient

      • X and Y = Variables




    • Substituting the given values, we get:



      • 8 - Viber = a + b(x - x^2)






  • Solving for n:


    • Since we have two equations, we can solve for n by eliminating the variables X and Y:



      • n = (r * sqrt(nΣX^2 - (ΣX)^2)) / sqrt(nΣY^2 - (ΣY)^2)
