Question

Eight trials are simulated. The results are shown in the table. Simulation 112 106 105 110 109 108 111 105 What is the estimated margin of error, using standard deviation? Enter your answer, rounded to two decimal places, in the box.

i took the test :)

Answer 2

The  margin of error of the 8 simulations is 0.89z

How to determine the margin of error?

The dataset is given as:

112 106 105 110 109 108 111 105

Using a graphing calculator, the standard deviation is:

σ =2.53

The  margin of error is then calculated using:

$E = z * \frac{\sigma}{\sqrt n}$

Where z represents the critical value

So, we have:

$E = z * \frac{2.53}{\sqrt 8}$

Evaluate

E = 0.89z
