Thank you so much for giving such clear explanations on how to do r studio. Currently in a class that is required for my major and I have been struggling so much. You made using r studio 10x more clearer!!!
Hi Charlene! Thank you for a simple explanation! However, I've got a question: how do you know, the assumptions were not violated? Does it appear somewhere, or do we need to write a separate code for normality and variance homogeneity tests?
My Hw is asking to chose an (beta a) level and alternative hypothesis, and indicate for each model in (a) and (b) whether you accept to reject the null hypothesis? Don't know what to do and I'm frustrated
hello, I need your help. I have been trying to conduct a t test in R, the code i entered is as follow: "t.test(Unit Price~Shipping Cost, data = SuperStoreUS_2015, var.equal=TRUE) Error: unexpected symbol in "t.test(Unit Price". i have done it many times on different computers, same result. I can't see what unexpected symbol R is talking about. Can you help?
