"As the legend tells, Isaac Newton discovered the law of universal gravitation after an apple fell on his head. What happened with this great apple after it bounced off Newton's head?" People who visited a certain website were asked this question. Of 257 people who answered this question during the last month, 30% replied that Newton ate the apple. Calculate the margin of error for this result. Round the percentage to one decimal place. Do not round intermediate steps. QUESTION: If 30% of 257 people replied that Newton ate the apple, the margin of error is?
Newton’s law of gravitation and the formula for centripetal acceleration can be used to show that: T^2=(4π^2/Gms)R^3 where G is the universal constant of gravitation and MS is the mass of the Sun.
