Sukie interviewed 125 employees at her company and discovered that 21 of them planned to take an extended vacation next year. What is the standard error?

The standard error is 0.033.

Step-by-step explanation:

We are given that Sukie interviewed 125 employees at her company and discovered that 21 of them planned to take an extended vacation next year.

Let = proportion of employees who planned to take an extended vacation next year

= = = 0.168

n = number of employees at her company = 125

Now, the standard error is calculated by the following formula;

       Standard error, S.E. =  

                                         =  

                                         =    = 0.033

Hence, the standard error is 0.033.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
