In a system of a sequence of operations, one process is to measure the angle

In a system of a sequence of operations, one process is to measure the angle at which fibers are glued to a sheet of base material. The correct angle is extremely important in the later processes. A Gauge R&R project is determined to study the uncertainty of the degree of the angle. A team of four members are chosen for the study. Each team member measures five specimens for three times. The same five specimens are used through the project.  The tolerance specification is ∓4 degree. The measurements are recorded in the attached Excel sheet. Use Minitab software to conduct gauge R&R study. Interpret the results
