A survey found that 89% of a random sample of 1024 American adults approved of cloning endangered animals. Find the margin of er

Kobotan [32]

Answer:

The margin of error for the survey is 0.016

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 1024

Sample proportion:

$\hat{p} = 89\% = 0.89$

We have to find the margin of error associated with a 90% Confidence interval.

Formula for margin of error:

$z_{stat}\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.10} = 1.64$

Putting the values, we get:

$M.E = 1.64\times (\sqrt{\dfrac{0.89(1-0.89)}{1024}})\\\\M.E=0.016$

Thus, the margin of error for the survey is 0.016

Question 1 (10 points)

Irina18 [472]

Answer:

Q1 d, Q2 c, Q3 d

Step-by-step explanation:

g(x)=-3x+1

g(x)=16 means that

-3x+1=16 subtract 1 from both sides

-3x=16-1 combine like terms and divide both sides by -3

x=-15/3=-5

g(x)=3x²+4x-1

g(2) means that x=2 so substitute

g(2)=3*2²+4*2-1=12+8-1=19

domain are the x values

range are the y values
