MrMuchimi

Answer:

standard error of the mean = 1.6960

Step-by-step explanation:

Given -

Mean (\overline{X}) = 53 minutes

Standard deviation ( s ) = 53.9 minutes

n = 1010

standard error of the mean  =  

\sigma _{\overline{X}}    =   \frac{s}{\sqrt{n}}

        = \frac{53.9}{\sqrt{1010}}

       =  1.6960

How do I solve this?? I'm lost
Alekssandra [29.7K]
Your insight that the function values differ by 5 every time is very important. So your f(x) will contain 5x as a term. You have to find a constant to add or subtract to make sure f(1)=-2.

f(x) = 5x-7 does the job.
