A research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, n = 1010 and x= 515 who said "yes" . Use a 99% confidence level. Identify the value of the margin of error E.

The margin of error is 0.041.

Step-by-step explanation:

Since we have given that

n = 1010

x = 515

So, it becomes

At 99% level of confidence ,

z = 2.58

So, Margin of error would be

Hence, the margin of error is 0.041.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
