Answer:

25 measurements need to be taken

Explanation:

Given:

individual uncertainty, [tex]u_i=1.5\ mm[/tex]

  • Let the uncertainty mean be [tex]u_m=0.3\ mm[/tex]

Now we have the relation as:

[tex]n=(\frac{u_i}{u_m})^2[/tex]

where:

n= number of measurements

[tex]n=(\frac{1.5}{0.3})^2[/tex]

[tex]n=25[/tex]  measurements need to taken in this case.
