Nationally, patients who go to the emergency room wait an average of 7 hours to be admitted into the hospital. Do patients at rural hospitals have a lower waiting time? The 10 randomly selected patients who went to the emergency room at rural hospitals waited an average of 6.2 hours to be admitted into the hospital. The standard deviation for these 10 patients was 1.6 hours. What can be concluded at the the αα = 0.01 level of significance level of significance?   The null and alternative hypotheses would be:       H0:H0:  ? μ p  Select an answer = > ≠ <         H1:H1:  ? μ p  Select an answer ≠ < = >       The test statistic ? t z Correct =  (please show your answer to 3 decimal places.)   The p-value =  (Please show your answer to 4 decimal places.)

Do political sclence classes require more writing than history classes? The 57 randornly selected political science classes assigned an average of 17.8 pages of essay writing for the course. The standard deviation for these 57 classes was 4 pages. The 58 randomly selected history classes assigned an average of 16.8 pages of essay writing for the course. The standard devlation for these 58 classes was 5.6 pages. What can be concluded at the a = 0.10 level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: Ho: Select an answerv Select an answerv Select an answerv H: Select an answerv Select an answerv Select an answerv b. The test statistic ?v = (please show your answer to 3 decimal places.) c. The p-value = d. The p-value is ?v a e. Based on this, we should Select an answerv the null hypothesis. f. Thus, the final conclusion is that ... (Please show your answer to 4 decimal places.) O The results are statistically significant…

One group of 50 students took a distance learning class, while another group of 25 took the same course in a traditional face-to-face classroom. Both group were given the same mid-term test. The average score of the distance learning group was 52.0 with a standard deviation of 15.4. The average score for the group who took the course in the traditional format was 58.0 with a standard deviation of 18.0. At a significance level of 0.1, can it be concluded that there is a difference in average score of students between the distance learning and face-to face instruction formats? Determine which of the following formulations of the hypotheses is appropriate and enter the corresponding number in the answer text box. Note: Index "v" refers to the population of students taking distance learning classes (virtual mode) and index "" refers to the population of students taking face-to-face classes (traditional mode). For example if you believe formulation number 4 below is the most appropriate…

Nationally, patients who go to the emergency room wait an average of 7 hours to be admitted into the hospital. Do patients at rural hospitals have a different waiting time? The 15 randomly selected patients who went to the emergency room at rural hospitals waited an average of 5.6 hours to be admitted into the hospital. The standard deviation for these 15 patients was 3 hours. What can be concluded at the the αα = 0.05 level of significance level of significance? a.  For this study, we should use Select an answer z-test for a population proportion t-test for a population mean  b.  The null and alternative hypotheses would be:       H0:H0:  ? μ p  Select an answer > ≠ < =         H1:H1:  ? p μ  Select an answer < > = ≠     c.  The test statistic ? z t  =  (please show your answer to 3 decimal places.) d.  The p-value =  (Please show your answer to 4 decimal places.) e.  The p-value is ? ≤ >  αα f.  Based on this, we should Select an answer reject accept fail to reject…
