Answer:
<em>Correlation coefficient = 0.945 ( approx) and weight of a student increases as the height of the student increases.</em>
<em>Step-by-step equation:</em>
<em>Here, value of x are 58, 59, 60, 62, 63, 64, 66, 68, 70</em>
<em>Value of y are, 122, 128, 126, 133, 145, 136, 144, 150, 151.</em>
<em>∑x = 570, ∑y= 1236, ∑ = 36234, ∑ = 170694</em>
<em>∑xy=78617</em>
<em>Thus the correlation coefficient,</em>
<em>Where n is the number of the term.</em>
<em>here n = 9</em>
<em>thus, correlation coefficient</em>
<em>r = </em>
<em>Thus, r= 0.94452987512</em>
<em>Which is closed to 0.95 and greater than 1</em>
<em>Therefore, weight of a student increases as the height of the student increases.</em>
