I think that options include:
A. With a high level of confidence, the republican defeated the democrats
B. the republican definitely defeated the democrats
C. the republican defeated the democrats with probability of 0.60
D. It is not possible to predict the winner because less than 1% of the voters were in the sample
Answer: Option D
Step-by-step explanation:
The result of this election cannot be predicted accurately as only 1000 voters out of 3,000,000 were sampled.
To get a good sample, the sample must be at least 10% of the total population and be a representative of the population but in this context, the sample is even less than 1% (30,000). Thus, the prediction might be inaccurate...
I think its 97200 i am sorry if it is wrong
A sample is best defined as 'a smaller group selected from a given population'.
A) To find x for f(x) = 0, substitute the given information and solve for x.
.. f(x) = 0 = -0.5x +2.5
.. 0.5x = 2.5 . . . . . . . . . . add 0.5x
.. x = 2.5/0.5 = 5 . . . . . . divide by the coefficient of x
f(5) = -0.5*5 +2.5 = 0
b) f(0) = -0.5*0 +2.5 = 2.5
