can you solve it with minitab and make steps in the software because i want to know how
Goal:
Analysis of variance(ANOVA)to analyze and interpret the data
The Problem: The tensile strength of Portland cement is being studied. Five different mixing techniques can be used economically. A completely randomized experiment was conducted and the following data were collected
