Answer:
DF
Step-by-step explanation:
the mid segment is a line that connects the midpoints.
Multiply 120 by .7 then take the product and add it to 120.
The formula for the standard error is this:
σM = σ / √N
where
σM is the standard error
σ is the standard deviation
N is the number of samples
So,
σM = 0.45 / √50
σM = 0.0636 or 6.36%
The standard error is 0.0636
