A researcher wants to find the effect of a special diet on systolic blood pressure. A sample of 7 adults was selected to start them on this diet for 3 months. Based on this information, can it be stated that systolic blood pressure changes with the special diet? What type of hypothesis test will allow us to reach a conclusion in the situation posed above? A. Null B. Bilateral C. Unilateral right rejection zone D. Unilateral left rejection zone
A Chi square test has been conducted to assess the relationship between marital status and church attendance. The obtained Chi square is 7.45 and the critical Chi square is 9.488. What may be concluded? Group of answer choices A.reject the null hypothesis, church attendance and marital status are independent B.fail to reject the null hypothesis, church attendance and marital status are independent C.Reject the null hypothesis, church attendance and marital status are dependent D.fail to reject the null hypothesis, church attendance and marital status are dependent
A researcher believes that there is a difference in how cautious male stray cats and female stray cats are when approaching people. He knows that the stray cat population is 50% male and 50% female. In order to test this hypothesis, he visits 15 different areas where stray cats live and records the gender of the first cat to approach him. He finds that 11 of the 15 cats that approach him are male. Using a sign test and an alpha of .05: Calculate the p-vlaue (or significance) of the obtained value (Hint: in a two - tailed test make sure to double the p-value).
My lawn needs mowing , but i do not want to mow if its going to start raining while I'm in the middle of the job. So i am looking at the sky evaluating the weather, using the null hypothesis: "It will rain within the next two hours". In this situation , what would a type I error be?
A commonly cited study says that 49% of students study less than 5 hours per week. A researcher does not think this is accurate and wants to show that the percentage of students that study less than 5 hours per week is not equal to 49%. Identify the null hypothesis, H0, and the alternative hypothesis, Ha, in terms of the parameter p.
If the decision rule for a one-tailed test of hypothesis is given as: Reject Ho if z<-2.36. What is the value of alpha?
Mario loves to listen to music and is convinced that listening to music while taking a test helps him get higher test averages. To prove this, Mario conducts a study amongst his classmates in his AMDM class. With the permission of his teacher, he randomly selects 15 out of 30 students in his class to listen to music during their next test. The remaining 15 students are not allowed to listen to music while they take their test. He intends to compare the test scores from each group, hoping to prove his hypothesis that listening to music while taking a test increases test scores. What is the variable of interest in this study? test grades the class Mario survey
For the given scenario, determine the type of error that was made, if any. (Hint: Begin by determining the null and alternative hypotheses.) A pharmaceutical company claims only 2% as the percentage of people taking a particular drug that experience significant side effects. One researcher claims that the percentage of people taking a particular drug that experience significant side effects is less than 2%. The researcher conducts a hypothesis test and fails to reject the null hypothesis. Assume that in reality, the percentage of people taking a particular drug that experience significant side effects is 0.5%. Was an error made? If so, what type?
Find the Type II error given that the null hypothesis, H0, is: there are no more than 15% of structures in the county were built without permits.And, the alternative hypothesis, Ha, is: a building inspector claims that more than 15% of structures in the county were built without permits. Select the correct answer below: The building inspector concludes that more than 15% of the structures in the county were built without permits when, in fact, no more than 15% of the structures were built without permits. The building inspector concludes that more than 15% of the structures in the county were built without permits when, in fact, more than 15% of the structures were built without permits. The building inspector cannot conclude that more than 15% of the structures in the county were built without permits when, in fact, no more than 15% of the structures were built without permits. The building inspector cannot conclude that more than 15% of the structures in the county were…
Suppose we want to compare the length of hospital stay for patients with the same diagnosis at two different hospitals. The results are shown in Table 9.10. 9.7 Why might a t test not be very useful in this case? 9.8 Carry out a nonparametric procedure for testing the hypothesis that lengths of stay are comparable in the two hospitals.
What is the value of the test statistic for a test with a null hypothesis that mu = 250, Xbar = 260 the standard error = 5 and n = 100?
A hypothesis test will be conducted and after summarinzing the data, the observed test statistic is z = 1.9. Explain how much evidence we have against the null hypothesis (H0) and for the alternative hypothesis (Ha) in each of the following sets of hypotheses: Explain the reason that the answer differs depending on the chosen alternative hypothesis.
