The Practice of Statistics for Business and Economics 4th edition by Moore et al., published by W.H. Freeman, helps students develop a working knowledge of data production and interpretation in a business and economics context, giving them the practical tools they need to make data-informed, real-world business decisions from the first day of class. The WebAssign component for this title features randomized questions taken directly from the text, video resources for each section, and links to an eBook (not shown).

Question 1 assesses basic knowledge of descriptive statistics using a fill-in-the-blank sentence with multiple-choice drop-down options.

Questions 2, 3 and 4 asks for scores, percentages, and quartiles based on a normal distribution. Question 2 also contains an essay part for open-ended responses to a critical thinking exercise.

Question 5 is a multi-part question involving the results of a survey. Students fill in a sentence describing how the variables are related, and choose a bar graph that accurately depicts the results.

Question 6 asks the student to calculate probabilities based on a distribution table.

Question 7 is a multi-part question based on a random variable that has a binomial distribution.

Question 8 demonstrates a t hypothesis test for the mean. The student identifies the null and alternative hypotheses, calculates the test statistic and p-value, and states the conclusion. In addition, the student also calculates a 95% confidence interval for the mean.

Questions 9 and 10 feature a downloadable data set in several formats that allows the student to perform statistical analyses in various programs such as Excel and JMP. Question 9 follows a chi-squared test of independence, and Question 10 handles a multiple regression equation. This demo assignment allows many submissions and allows you to try another version of the same question for practice wherever the problem has randomized values.
