Prof. Holman, I won’t be in class today as I just found out my mother has cancer. She has had it before but now its in stage four. I am going to see her now. I do have a question about the home test. You want us to estimate the mean for the whole US and our hint was the population. I don’t understand what you mean. Can you explain that to me, I would appreciate it. I will be in class for the test on Wednesday.
Thank you, Frank.
P.S. I check my e-mail regularly.
