1.

An experimental measurement has a result ( 4.5 ± 0.3)m , and a predicted value of 5.2m. How many standard deviations is the experimental measurement from the predicted value? What is the percent age uncertainty? What is the percent difference between the experimental value and the predicted value?

2. Look at the results of calculations made in #1, what can be said of the measurement in

terms of the predicted value? Explain.

3. Looking again at the results in #1, would you say the experiment used a precise method of

measurement? Explain

Explanation / Answer

2.33 standard deviations .

percentage uncertainity=.3/4.5 *100=6.66 %

percent difference=(5.2-4.5)/4.5=15.556 %
