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. Select the appropriate null and alternative hypotheses. Note, two of the choices below are correct and equivalent, select the two that work. H. :The distribution of the format of the book used by the students does not follow the professor's predictions. HA : The distribution of the format of the book used by the students follows the professor's predictions. H. : There is some difference from the stated proportions HA : Phard = 0.6, P print 0.25, ponline 0.15 H. :The distribution of the format of the book used by the students follows the professor's predictions. HA : The distribution of the format of the book used by the students does not follow the professor's predictions. H. : Phard = 0.6, P print 0.25, ponline 0.15 HA : There is some difference from the stated proportions

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. **Select the appropriate null and alternative hypotheses. Note, two of the choices below are correct and equivalent, select the two that work.** --- 1. - \( H_0 \): The distribution of the format of the book used by the students does not follow the professor’s predictions. - \( H_A \): The distribution of the format of the book used by the students follows the professor’s predictions. 2. - \( H_0 \): There is some difference from the stated proportions - \( H_A \): \( p_{\text{hard}} = 0.6, p_{\text{print}} = 0.25, p_{\text{online}} = 0.15 \) 3. - \( H_0 \): The distribution of the format of the book used by the students follows the professor’s predictions. - \( H_A \): The distribution of the format of the book used by the students does not follow the professor’s predictions. 4. - \( H_0 \): \( p_{\text{hard}} = 0.6, p_{\text{print}} = 0.25, p_{\text{online}} = 0.15 \) - \( H_A \): There is some difference from the stated proportions
