Question 1

1- You have ten fingers and measure their lengths.

2- Select six fingers and determine the range of mean length of all your ten fingers with 1.5% and 3% of uncertainty.

3- Which six fingers that you have selected for measurement and justify your selection?

4- Based on the uncertainty percentage in (1), determine the maximum length and minimum length of your fingers.

With a 93% certainty, how many fingers do you have to measure to produce an error of 1mm, and 2mm, respectively. (Note: error is the difference between mean of all your fingers and the mean of your selected six fingers).

Question 2

1- You have ten fingers but you can only measure the length of six fingers.

2- Select six fingers and determine the range of mean length of all your ten fingers with 1.5% and 3% of uncertainty.

3- Which six fingers that you have selected for measurement and justify your selection?

4- Based on the uncertainty percentage in (1), determine the maximum length and minimum length of your fingers.

With a 93% of certainty, how many fingers that you have to measure in order to produce an error of 1mm, and 2mm, respectively. (Note: error is the difference between mean of all your fingers and the mean of your selected six fingers).
