Correlation coeficient is 0,945. As it is positive the relation between height and weight is direct so this indicate that weight increase as the height increase

Answer 2

Answer:

Step-by-step explanation:

Given is the table

Height Weight

 

58 122

59 128

60 126

62 133

63 145

64 136

66 144

68 150

70 152

 

Mean 63.33333333 137.3333333

sr=td dev 4.092676386 10.89724736

r 0.944529875  

Since r is very mch near to 1 we find that height and weight are strongly positive correlated
