Answer:

b) 65.08

ii) 0.75

Step-by-step explanation:

x(Kg): 62 63 64 65 66 67 68

Frequency(f): 1 5 11 15 10 6 2

xf: 62 315 704 975 660 402 136

b) mean(X) = ∑xf/N = 3254/50 = 65.08

c) x - X : -3.08 -2.08 -1.08 -0.08 0.92 1.92 2.92

(x - X)²: 9.49 4.33 1.17 0.0064 0.85 3.69 8.53

ii) Standard deviation(S.D.): √(∑(x - X)²/N = √(28.0664)/50 = √0.5613

∴ S.D.= 0.75

(3/5,4,5)

Generally the value for $\theta$ is mathematically given by

$cos \theta = 3/5\\sin \theta = 4/5\\\theta = cos^-1 (3/5 )$

$\theta = 53.13 degrees$
