Answer to Question #225800 in Statistics and Probability for saqlain

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).
