    • Hi @facebook-100003335725011:disqus – I had to get my colleague to test this since I’ve got a Mac so I can’t use Minitab. He downloaded the data and ran it through Minitab 17 with the instructions and it worked (though he said the graph looks slightly different because of a data point at $290). Do you have Minitab 17?
