Newton's Law of Gravitation:
Statement: According to this law, when two mass bodies are separated at finite distance then there must be an attractive force experience by them which is directly proportional to the product of their masses and inversely proportional to the square of their separation.
Consider two mass bodies m1 & m2 be kept at distance d. Then the force of attraction F is given as
Now, from above equations, we have
or,
Here is the universal gravitational constant.
Using the z-distribution, it is found that the needed sample sizes are:
a) 242
b) 1842
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of
, we have the following confidence interval of proportions.
In which z is the z-score that has a p-value of .
The margin of error is:
99% confidence level, hence, z is the value of Z that has a p-value of
, so
.
Item a:
The estimate is:
The sample size is <u>n for which M = 0.03</u>, then:
Rounding up, a sample of 242 is needed.
Item b:
No prior estimates, hence is used.
Rounding up, a sample of 1842 is needed.
