**Hypothesis Testing and Errors**Assume that a hypothesis test of the given claim will be conducted. Identify the type I or type II error for the test.The principal of a school claims that the percentage of students at his school that come from single-parent homes is 11%. Identify the type II error for the test.- ○ Fail to reject the claim that the percentage of students that come from single-parent homes is equal to 11% when that percentage is actually 11%.- ○ Reject the claim that the percentage of students that come from single-parent homes is equal to 11% when that percentage is actually 11%.- ○ Reject the claim that the percentage of students that come from single-parent homes is equal to 11% when that percentage is actually less than 11%.- ○ Fail to reject the claim that the percentage of students that come from single-parent homes is equal to 11% when that percentage is actually different from 11%.**Note:** Moving to another question will save this response.

Solution Given the claim is the percentage of students at his school that come from single parent…

Marketers believe that 69.6 % of adults in the U.S. own a cell phone. A cell phone manufacturer believes a larger proportion have a cell phone. 31 adults living in the U.S. are surveyed, of which, 6 report that they have a cell phone. Using a 0.05 level of significance test the claim. The correct hypotheses would be: Ho:p ≤ 0.696 HA P 0.696 (claim) O Ho:p> 0.696 HA:P < 0.696 (claim) O Ho: p= 0.696 HA:P 0.696 (claim) Since the level of significance is 0.05 the critical value is 1.645 3 places) The test statistic is: The p-value is: (round (round to 3 places)
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? Click the icon to view the table. ..... Determine the null and alternative hypotheses. A. Ho: Polygraph testing is accurate. H1: Polygraph testing is not accurate. More info B. Ho: Whether a subject lies is independent of the polygraph test indication. H1: Whether a subject lies is not independent of the polygraph test indication. Did the Subject Actually Lie? No (Did Not Lie) Yes (Lied) C.

Classify the conclusion of the hypothesis test as a Type I error, a Type II error, or a correct decision. In 1992, the average math SAT score for students at one school was 479. Five years later, a teacher wants to perform a hypothesis test to determine whether the average math SAT score of students at the school has changed from the 1992 mean of 479. The hypotheses are: H0:μ =479 H1:μ ≠479 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 1992 mean of 479.
