Answer:
Chebyshev's Theorem states that at least 75% of all scores fall within 2 standard deviations from the mean and at least 89% fall within at least 3 standard deviations from the mean.
Therefore,
x-2*sd= 3740
x+2*sd=4860
Therefore 2x=8600
x=4300
2sd=4860-4300 =560
Sd= 280
Mean=4300kg, sd= 280kg
