Answer:
Domain 
Range 
Step-by-step explanation:
Domain : Domain of a function
is the set of all possible values of
for which
exists.
Range : range of a function
is the set of all possible values of
.
Here 
can be any value from
to
.

hence possible value of
can be any value between
and 

let 

so
.
hence
can have any value between
.
Range

See explanation below
Step-by-step explanation:
Since each time after the person gets off the scale, the reading is 2 lb the person's weight must be near the mean of
148-2, 151-2, 150-2, 152-2; that is to say, near the mean of 146, 149, 148, 150 = (146+149+148+150)/4 = 148.25
We could estimate the uncertainty as <em>the standard error SE
</em>
where
<em>s = standard deviation of the sample
</em>
<em>n = 4 sample size.
</em>
Computing s:
So, the uncertainty is 1.479/2 = 0.736
<em>It is not possible to estimate the bias, since it is the difference between the true weight and the mean, but we do not know the true weight.
