Question
A professor using an open source introductory statistics book predicts that 60% of the students will purchase a hard copy of the book, 25% will print it out from the web, and 15% will read it online. At the end of the semester he asks his students to complete a survey where they indicate what format of the book they used. Of the 126 students, 71 said they bought a hard copy of the book, 30 said they printed it out from the web, and 25 said they read it online. Use Rguroo to carry out this hypothesis test. 1. The chi-square test statistic is equal to (Round to 2 decimal places) 2. The degrees of freedom is 3. The p-value is (Round to four decimal places) 4. The p-value is tells us that the sample from the students is consistent with the hypothesis (enter "null" for null and "alternative" for alternative.)
