Answer:
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.
</em>

Answer:
Top Left
Step-by-step explanation:
Shaded circle means it will be Greater than or equal to or Less then or equal to. The answwers are less that or equal to 75 so s is less than or equal to 75
Answer:

Step-by-step explanation:
<h3><u>TO SOLVE:</u></h3>
Isolate by the x on one side of the equation.
<h3><u>SOLUTIONS:</u></h3>
First, subtract 3x from both sides.

Solve.

Sides are NOT equal.

Therefore, there are no solutions.
