Question A professor is trying to determine if her students guessed on a certain multiple choice question. She expects that if the students guessed, the distribution of answers would be uniform for that question. She compares the observed distribution of answers with the uniform distribution. The professor conducts a chi-square Goodness-of-Fit hypothesis test at the 5% significance level. (a) The null and alternative hypotheses are: • Ho: The student answers have the uniform distribution. • Ha: The student answers do not have the uniform distribution. (b) xở = 13.167. (C) X6os = 7.815. %3D (d) What conclusions can be made? Select all that apply. Select all that apply: We should reject Ho. We should not reject Ho. At the 5% significance lèvel, there is sufficient evidence to conclude that the students were not guessing. O At the 5% significance level, there is not enough evidence to conclude that the students were not guessing.

According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. In that year, Alaska had 321 complaints of identity theft out of 1,432 consumer complaints ("Consumer fraud and," 2008). Does this data provide enough evidence to show that Alaska had a lower proportion of identity theft than 23%? Test at the 5% level. (i) Which of the following statements correctly defines the null hypothesis HO? A. μ = 321 B. p < 0.23 C. p = 0.23 D. μ < 321 Enter letter corresponding to correct answer (ii) Which of the following statements correctly defines the alternative hypothesis HA? A. μ = 321 B. p < 0.23 C. p = 0.23 D. μ < 321 Enter letter corresponding to correct answer (iii) Enter the level of significance α used for this test: Enter in decimal form.

Because you suspect that the wheel is not fair, you watch a random sample of 100 people play the game. Here are the findings: Color Red White Green Yellow Observed 48 22 25 Expected 25 25 25 25 A chi-square goodness of fit test was conducted to determine whether the data provide convincing evidence that the wheel is not fair. The test statistic was 37.52. Which of the following statements is true? (A) At the significance level a = 0.05, the data do not provide convincing evidence that the wheel is not fair. (B) At the significance level a = 0.05, the data provide convincing evidence that the wheel is not fair. (C) No valid conclusion can be made because the observed frequency for one cell is 5. (D) The chi-square statistic has 100 – 1 = 99 degrees of freedom. %3D (E) The wheel may not be fair, but the game is fair because all of the expected values are equal.
Suppose a 95% confidence interval for the difference in test scores between Class 1 and Class 2 (in that order) is the following: 9 +/− 2. These results were based on independent samples of size 100 from each class. Now suppose you switch the order of Class 1 and Class 2 in your analysis but keep the data labeled correctly in terms of which class they came from. Which of the following statements is false? A) You can't do it this way. You'll get negative numbers for the difference in the means and/or negative numbers for the standard error. B) You are confident that the average for Class 2 is 7 to 11 points lower than for Class 1. C) You are still confident that the classes have significantly different mean scores. D) Your 95% confidence interval will now be entirely negative: from −7 to −11.
(c) Calculate the test statistic. d) Decide whether to reject or fail to reject the null hypothesis. Then interpret the decision in the context of the original claim.
Test the claim that the mean GPA of night students is larger than 2 at the 0.10 significance level. The null and alternative hypothesis would be: Ho p= 0.5 Ho:p ≥ 0.5 Ho:p ≤ 0.5 H₁:p 0.5 H₁:p 0.5 The test is: right-tailed left-tailed two-tailed Based on a sample of 25 people, the sample mean GPA was 2.02 with a standard deviation of 0.07 The p-value is: Based on this we: Ho:μ = 2 Ho:μ ≥ 2 Ho: ≤2 H₁:μ ‡ 2 H₁:μ 2 Reject the null hypothesis O Fail to reject the null hypothesis (to 2 decimals)
This question: 5 point(s) possible In a study of 823 randomly selected medical malpractice lawsuits, it was found that 477 of them were dropped or dismissed. Use a 0.01 significance level to test the claim that most medical malpractice lawsuits are dropped Which of the following is the hypothesis test to be conducted? OA. Ho: p=0.5 H₁: p>0.5 OC. Ho: p=0.5 H₁: p 0.5 H₁: p=0.5 OF. Ho: p0.5 H₁: p=0.5 WA (C) dismissed.
The table below includes results from polygraph (lie detector) experiments conducted by researchers. In each case, it was known if the subjected lied or did not lie, 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 truth and lies? Determine the test statistic. (Round ofd to 3 decimal places) Find the P-Value What is the conclusion? (In case you are using excel, I will appreciate if you explain the steps of finding the test statistic and the P-value....But this is not a must)
In a hypothesis test, the researcher does not reject the null hypothesis at 5% level of significance. Which of the following conclusions necessarily follows? The p-value of the test was less than 10%, O None of them. O The researcher performed a two-tailed test with 10% significance level. O The null hypothesis would not have been rejected at 1% level of significance. The p-value of the test was less than 3%.
