Explanation / Answer
correlation=-0.689 beteween x and y is calculated using ms-excel command=correl(x,y)
after adding two value the correlation =-0.662
percent return(x) new adults(y) 76 4 71 6 83 9 49 10 76 11 62 15 49 16 48 16 63 18 47 16 63 19 47 22 36 20 correlation(x,y)= -0.689Related Questions
