When evaluating a survey, Jody saw that 54% of the respondents think that the minimum age of those awarded a driver's license sh

ould be raised, while 46% think it should remain the same. The margin of error was ±5%. Which statement is true?
The population proportion of those who think the driving age should be raised is definitely greater than the proportion who think it should remain the same.



The population proportion of those who think the driving age should be raised is definitely less than the proportion who think it should remain the same.



The population proportion of those who think the driving age should be raised may or may not be greater than the proportion who think it should remain the same.



The population proportion of those who think the driving age should be raised is definitely equal to the proportion who think it should remain the same.

Since the margin of error is 5%, the minimum of supporters will be less than the maximum of disapprovers. 

So the third option will be correct. You cannot make certain conclusions based on this survey.

prisoha [69]

Answer:

The correct option is B.

Step-by-step explanation:

The given equation are

y=4x-3

y=-5x+9

On solving both the equation, we get

4x-3=-5x+9

4x+5x=9+3

9x=12

9x=\frac{12}{9}=\frac{4}{3}

Put this value in the given equation.

y=4(\frac{4}{3})-3

y=\frac{16}{3}-3

y=\frac{16-9}{3}

y=\frac{7}{3}

The solution of the given system of equation is

(\frac{4}{3},\frac{7}{3})=(1.333,2.333)\approx (1.3,2.3)

The best approximation of the exact solution is (1.3,2.3). Therefore the correct option is B.

After calculating the sample size needed to estimate a population proportion to within 0.05, you have been told that the maximum
Svetlanka [38]

Answer:  40000

Step-by-step explanation:

The formula to find the sample size is given by :-

n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2, where p is the prior estimate of the population proportion.

Here we can see that the sample size is inversely proportion withe square of margin of error.

i.e. n\ \alpha\ \dfrac{1}{E^2}

By the equation inverse variation, we have

n_1E_1^2=n_2E_2^2

Given : E_1=0.05   n_1=1000

E_2=0.025

Then, we have

(1000)(0.05)^2=n_2(0.025)^2\\\\\Rightarrow\ 2.5=0.000625n_2\\\\\Rightarrow\ n_2=\dfrac{2.5}{0.000625}=4000

Hence, the sample size will now have to be 4000.
