What are the null and alternative hypotheses? A. H0: The two variables, x and y, are associated. Ha: The two variables, x and y, are not associated. B. H0: The variable x is dependent upon y. Ha: The variable y is dependent upon x. C. H0: The two variables, x and y, are not associated. Ha: The two variables, x and y, are associated. The P-value is (Round to three decimal places as needed.) What is the conclusion of the independence test? A. Do not reject H0. The data provide sufficient evidence of an association. B. Reject H0. The data provide sufficient evidence of an association. C. Do not reject H0. The data do not provide sufficient evidence of an association. D. Reject H0. The data do not provide sufficient evidence of an association.
A hypothesis test is conducted in order to determine the average weight of a Kit Kat bar.using the following null and alternative hypotheses: H0: The average weight of a Kit Kat bar is 1.5 ounces. HA: The average weight of a Kit Kat bar is greater than 1.5 ounces. Using complete sentences, explain what both a Type 1 and Type 2 error would be in context of this hypothesis test.
Construct hypotheses based on a given observation and determine if a given scenario is using deductive or inductive reasoning. 3. Jackie observed that most of the houses in her neighborhood did not set out recycling cans on trash pick-up day. She wondered if the lack of participation was due to apathy and decided to conduct a formal survey. Write a specific, testable research hypothesis and null hypothesis for Jackie’s observation. Justify your reasoning.
Classify the conclusion of the hypothesis test as a Type I error, a Type II error, or a correct decision. In 1995, the average math SAT score for students at one school was 486. Five years later, a teacher wants to perform a hypothesis test to determine whether olo the average math SAT score of students at the school has changed from the 1995 mean of 486. The hypotheses are: H,:u=486 Hu#486 Suppose that the results of the sampling lead to rejection of the null hypothesis. Classify that conclusion as a Type I error, a Type II error, or a correct decision, if in fact the average math SAT score of students at the school has changed from the 1995 mean of 486.

The table to the right includes results from polygraph experiments. In each case, it was known if the subject lied or not, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truths and lies? State the null and the alternative hypotheses. Choose the correct answer below. O A. Ho: The row and column variables are independent. H₂: The row and column variables are dependent. OB. Ho: At least one of the values is different from the others. Ha: All values in the table are equal. OC. Ho: All values in the table are equal. Ha: At least one of the values is different from the others. Polygraph indicated that subject lied Polygraph indicated that subject did not lie O D. Ho: The row and column variables are dependent. H₂: The row and column variables are independent.

To test the effectiveness of a business school preparation course, 8 students took a general business test before and after the course. The results are given below. Student Exam Score Before the Course Exam Score After the Course 1 720 700 2 740 770 3 900 950 4 700 710 5 500 580 6 840 900 7 820 840 8 640 650 Use an appropriate hypothesis test, at 0.05 level of significance, to determine whether there is evidence of a difference between before and after scores of the students. What assumption is necessary to perform the hypothesis test in (a)? Construct a 95% confidence interval estimate of the mean difference in before and after scores. Interpret the interval. What is your decision based on this confidence interval estimate?

For the given hypothesis test, explain the meaning of the kind of error, as requested. A statistics student has heard that about 25% of the students on his campus attend sporting events weekly. He wants to know if statistics students attend events in the same proportions as the general student body. Explain what the second type of error would be in this case (where the student fails to reject a null hypothesis that is actually false). O A. The second kind of error would be saying that statistics students attend sporting events in much higher proportions than the student body as a whole, even though they actually have the same attendence proportion. B. The second kind of error would be saying that there is no difference in the attendence of statistics students and the student body as a whole at sporting events, even though there really is. O C. The second kind of error would be saying that there is no difference in the attendence of statistics students and the student body as a whole at…
