Use the sample data and confidence level given below to complete parts​ (a) through​ (d). In a study of cell phone use and brain hemispheric​ dominance, an Internet survey was​ e-mailed to 2349 subjects randomly selected from an online group involved with ears. 1067 surveys were returned. Construct a 95​% confidence interval for the proportion of returned surveys.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

5+2x=a

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒ ⇒

factorizing, we get that:
