I was working on the sample problems for 7.6 and got them right, for the most part, but I rounded to the nearest percentage. Will you mark it wrong if we do this on the exams?
(i.e. For my problem 2, my answer was.... We are 90% confident that the true rate of new marriages ending in divorce is between 51% and 55%.)

Hi Alexa,
The exams are going to be multiple choice this summer, so you will simply round your answers to the same decimal place that all of the answer choices are rounded to. You will not have the same answer rounded to different places on the exam.
