Is there a particular acid reflux drug that is more effective? To answer this question, we will use a random sample of patients suffering from acid reflux and randomly place them in three groups. One group will take Prilosec, one group will take Nexium, and one group will take Zantac. We will perform a hypothesis test for homogeneity, looking at the proportion of patients from each group whose acid reflux improves after taking the drug (results shown in the table below). Test at the a = 0.10 level of significance. Which would be correct hypotheses for this test? Ho: p1 = p2 = p3; Hi : at least one proportion is different than the others O Ho:M1 = 12 = M3; H1: MI # #2 # #3 O Ho:P1 = p2 = P3 ; HI :P1 / P2 # P3 H: The three proportions are different; H1 : The three proportions are the same Sample data: Condition Improved Condition Not Improved Prilosec 31 24 Nexium 35 16 Zantac 21 14 Test Statistic (2 decimal places): Give the P-value (4 decimal places, if less than 0.001 answer 0): Which is the correct result: Reject the Null Hypothesis Do not Reject the Null Hypothesisthey use on their homework? Of the randomly selected community college students 67 used a computer, 104 used a calculator with built in statistics functions, and 25 used a table from the textbook. Of the randomly selected university students 44 used a computer, 88 used a calculator with built in statistics functions, and 27 used a table from the textbook. Conduct the appropriate hypothesis test using an or = 0.05 level of significance. a. What is the correct statistical test to use? O Paired t-test O Goodness-of-Fit Independence O Homogeneity b. What are the null and alternative hypotheses? Ho : The distribution of the technology that community college statistics students use for their homework is the same as the distribution of the technology that university statistics students use for their homework. Type of student and type of technology used for statistics homework are independent. The distribution of the technology that community college statistics students use for their homework is not the same as the distribution of the technology that university statistics students use for their homework. Type of student and type of technology used for statistics homework are dependent. H1: The distribution of the technology that community college statistics students use for their homework is the same as the distribution of the technology that university statistics students use for their homework. The distribution of the technology that community college statistics students use for their homework is not the same as the distribution of the technology that university statistics students use for their homework. Type of student and type of technology used for statistics homework are dependent. Type of student and type of technology used for statistics homework are independent. C. The test-statistic for this data = (Please show your answer to 2 decimal places.) d. The p-value for this sample = "Please show your answer to 4 decimal places.)
