Question

Consider the following data set, in which shrinkage is measured once again at low injection
velocity and high injection velocity. However, this time the mold temperature is raised to a high
level and held constant.
Shrinkage values at low injection velocity:
76.20 76.09 75.98 76.15 76.17 75.94 76.12 76.18 76.25 75.82

Answer 1

If the question is to check that data set, we can employ R.

The output from the shapiro.test( ) function suggests that the shrinkage values at low injection velocity dataset is normally distributed (p = 0.2675 > 0.05).
