USE THE 8-STEP HYPOTHESIS TESTING In a study by Xiao and Shi (A-14), researchers studied the effect of cranberry juice in the treatment and prevention of Helicobacter pylori infection in mice. The eradication of Helicobacter pylori results in the healing of peptic ulcers. Researchers compared treatment with cranberry juice to "triple therapy (amoxicillin, bismuth subcitrate, and metronidazole) in mice infected with Helicobacter pylori. After 4 weeks, they examined the mice to determine the frequency of eradication of the bacterium in the two treatment groups. The following table shows the results. Triple therapy Cranberry juice No. of Mice with Helicobacter pylori Eradicated Yes No 8 2 2 8 Source: Shu Dong Xiao and Tong Shi, "Is Cranberry Juice Effective in the Treatment and Prevention of Helicobacter Pylori Infection of Mice," Chinese Journal of Digestive Diseases, 4 (2003), 136-139. May we conclude, on the basis of these data, that triple therapy is more effective than cranberry…
If the researcher wants to do a 2 tailed hypothesis test based on the data to generalize the relationship, what would the null and alternative hypothesis be? (in words and symbol notation).
The health board of a major city wants to know if people who have different types of healthcare coverage (HMO, Medicare/Medicaid, or no insurance) go to different types of hospitals (privately-funded, government-funded, or free clinic) when they are injured. Using the data below, test the null hypothesis that type of insurance does not affect which hospital type they choose.

Which of the following is NOT true for conducting a hypothesis test for independence between the row variable and column variable in a contingency table? Question content area bottom Part 1 Choose the correct answer below. A. The number of degrees of freedom is (r−1)(c−1), where r is the number of rows and c is the number of columns. B. The null hypothesis is that the row and column variables are independent of each other. C. Tests of independence with a contingency table are always right-tailed. D. Small values of the χ2 test statistic reflect significant differences between observed and expected frequencies.
The mean SAT score in mathematics is 478 . The founders of a nationwide SAT preparation course claim that graduates of the course score higher, on average, than the national mean. Suppose that the founders of the course want to carry out a hypothesis test to see if their claim has merit. State the null hypothesis H0 and the alternative hypothesis H1 that they would use. H0 : H1 :
(a) Identify the claim and state H0 and Ha. (b) Use technology to find the P-value. (c) Decide whether to reject or fail to reject the null hypothesis and (d) interpret the decision in the context of the original claim.
A blind taste test is conducted to determine which of two colas, Brand A or Brand B, individuals prefer. Individuals are randomly asked to drink one of the two types of cola first, followed by the other cola, and then asked to disclose the drink they prefer. Results of the taste test indicate that 45 of 100 individuals prefer Brand A. Complete parts a through c. ..... (a) Conduct a hypothesis test (preferably using technology) Ho: p= Po versus H,: p# Po for po = 0.34, 0.35, 0.36, ., 0.54, 0.55, 0.56 at the a = 0.05 level of significance. For which values of po do you not reject the null hypothesis? What do each of the values of po represent? Do not reject the null hypothesis for the values of po between (Type integers or decimals as needed.) and inclusively. (b) Construct a 95% confidence interval for the proportion of individuals who prefer Brand A. The lower bound is The upper bound is (Round to three decimal places as needed.) (c) Suppose you changed the level of significance in…
A study suggests that the average college student spends 20 hours per week preparing for classes. Your research team believes this claim is an overestimate and decides to collect their sample for a hypothesis test. a) Fill in the missing value in the null hypothesis below: H0 : u0 = b) write out your teams' alternative hypothesis in notation form: H1: c) your team randomly recruits 35 students for your study. Based on this sample size, should you use z or t-test statistics for your hypothesis test? Explain your reasoning? d) write out the decision rule for your hypothesis test. Make sure to include the appropriate z or t critical value. You may assume a 5% significant level e) on average, your team found that the 35 subjects in your sample spent 15.8 hours a week preparing for classes with a standard deviation of 8.9 hours. use this information to calculate the appropriate test statistics. f) make a decision using the decision rule in (d) and the calculated test statistics in…
A blind taste test is conducted to determine which of two colas, Brand A or Brand B, individuals prefer. Individuals are randomly asked to drink one of the two types of cola first, followed by the other cola, and then asked to disclose the drink they prefer. Results of the taste test indicate that 58 of 100 individuals prefer Brand A. Complete parts a through c. (a) Conduct a hypothesis test (preferably using technology) H0:p=p0 versus H1:p≠p0 for p0=0.47,0.48,0.49,...,0.67,0.68,0.69 at the α=0.05 level of significance. For which values of p0 do you not reject the null hypothesis? What do each of the values of p0 represent? Do not reject the null hypothesis for the values of p0 between _ and _,inclusively.
Students in a Psychology Stats class gathered 1st and 2nd year university students to gather self-report data on UFO, sightings during the past year. A year later the same students took the survey after taking LSD. The results of the self-report survey are as follows: Participant ID UFO sightings UFO sightings before LSD after LSD 1 1 2 1 3 2 2 4 1 3 3 1 7 3 A) State the Null and Alternative Hypothesis. B) Find the calculated "t" value and the critical "t" value C) State weather to accept or reject the Null Hypothesis
