I am taking Elementary Statistics this summer and have a TI-83 plus calculator, I did not do very good in algebra but passed. I am thinking of buying the book, does it come with training on how to use the calculator? I was not able to fin the app that says stats?
Thank you, and please let me know I would like to pass this class and I only have a 10 week class

Trish,
The TI-83 guide walks you through the steps to using the calculator for a wide variety of problems. It comes free with the statistics handbook if you buy it here on the site.
Good luck!

The filling machine used by a dairy company to fill 1kg containers of yoghurt produces output which follows a normal distribution with mean 1030g (slightly more than 1kg) and standard deviation 20g. Suppose that the company can change either the mean or the standard deviation of the filling amount (but not both). If they require the probability of underfilling a container (i.e. contents less than 1000g) to equal 0.05, find (i) the smallest value of the mean; and (ii) the largest value of the standard deviation that satisfies this requirement (in each case to the nearest gram).

I have taken Elementary Statistics /Math 300 through Aleks. And I failed it. This is the last class for my BA degree, and I am worried I will not pass it again. Will your book help me get through this class. I am on SS only and have to pay for this class which is going to hurt me a lot. I want to order you book it looks like it will give me some hope in this class. If I order this how long will it take it to get to me?

Thank you for your time

Hi, Mary Ann,
The book is an e-book (actually a collection of 4 books), so it’s an instant download. When I taught statistics, students who used the book tended to get one grade higher, so for those struggling, it often resulted in a pass. You might also want to look at our YouTube channel, which has hundreds of videos to walk you through popular statistics topics. We also have a forum, where you can ask questions if you get stuck.
I wish you the best of luck with passing your class,
Stephanie
