Without knowing the structure and methods of his study,
and the methods of selecting the population sample, we
can't tell whether his conclusion is justified or not.

Answer:
The gravitational force is 3.509*10^17 times larger than the electrostatic force.
Explanation:
The Newton's law of universal gravitation and Coulombs law are:
Where:
G= 6.674×10^−11 N · (m/kg)2
k = 8.987×10^9 N·m2/C2
We can obtain the ratio of these forces dividing them:
--- (1)
The mass of the moon is 7.347 × 10^22 kilograms
The mass of the earth is 5.972 × 10^24 kg
And q1=q2=Na*e=(6.022*10^23)*(1.6*10^-19)C=9.635*10^4 C
Replacing these values in eq1:
Therefore
This means that the gravitational force is 3.509*10^17 times larger than the electrostatic force, when comparing the earth-moon gravitational field vs 1mol electrons - 1mol protons electrostatic field

<span>The fact that muscles will improve in strength and conditioning in response to resistance training is called MUSCLE HYPERTROPHY.
This occurs because during resistance training the muscles develop very small tears, called micro-tears, that eventually heal and become scar tissues. As the scar tissues continue to increase, muscle fibers are said to bulk up creating that big and muscular physique that you see in people who are into resistance training.</span>
