Determine the type of measurement by classification

[Miristeri]

Homework Statement

1) It is necessary to calculate the error using the small sample method (Student distribution).
2) Calculate the instrumental error

Relevant Equations

The equation is missing

I was only able to determine the type of measurement, it turns out to be direct - single. I can't find 1) and 2) of the homework instructions. I have the following data:Voltage:
U1, B = 15.05
U2, B = 15,06
U3, B = 15,05
Relative error of the multimeter
ΔU/U, % = 4

Help please
