Introductory Business Statistics, 2e, OpenStax, Holmes

Data • Probability • Sampling • Hypothesis Testing • Regression

Coverage
13 core units
Skill Range
Easy to very difficult
Extra Support
Solutions manual available

Business Statistics can feel manageable when you watch examples in class. Then the exam puts formulas, tables, and word problems together on one page. Suddenly, small mistakes cost big marks. That is why students need more than notes and homework alone.

Designed for your exact course

This Test Bank is designed for use with the Second Edition of Introductory Business Statistics by OpenStax. It works well for Introductory Business Statistics and Business Analytics courses where students study data, probability, sampling, regression, and hypothesis testing. Openstax is known for its high quality affordable books. This title is also seen as one of the best selling introductory business stat textbooks.

Made for different levels of students

The questions and problems range from quite easy to very difficult. Some are easy to categorize, but others are not. What might be a hard problem to one set of students might be easy to another set. These differences arise due to differences in students’ innate ability and backgrounds and to the time an instructor spends on a topic.

How can this Test Bank help you?

To further alleviate guessing-induced biases, a super multiple choice system has been used. That gives you a better way to practice before quizzes, midterms, and finals.
