hello professor, for homework 7.4 the standard deviation takes a really long time to find. I just wanted to ask whether the standard deviation will be given on the test, or will we have to find it ourselves?

-Thank you

Good morning Professor! Please clarify as to what I am expected to bring to the exam today...Required tables: Z, T, and P-value? Also I heard you are allowing an index card with all formulas. Let me know if this is correct. Thanks!

QUESTION 3 of 4

Hi professor. On the mixed review for chapter 2, number 64 has confused me. For summation notation, I have no problem figuring out the problems and the steps when given a set of numbers, but number 64) almost has us work this back words without a given set. Is this what the question will look like on the exam instead of what was shown in class? Could you give me a hint on how to start this problem...

thanks in advance

QUESTION 4 of 4

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%.)
