Suppose that in a random selection of 100 colored candies, 22% of them are blue. The candy company claims that the percentage of blue candies is equal to 26%. Use a 0.10 significance level to test the claim. 1. Identify the null and alternative hypothesis for this test. 2. Identify the test statistic and the P value for this hypothesis test. 3. Identify the conclusion for this hypothesis test.
An online poll asked: "Do you believe the Loch Ness monster exists?" Among 20,139 responses, 68% were "yes." Use a 0.10 significance level to test the claim that most people believe that the Loch Ness monster exists.

Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion. K A person randomly selected 100 checks and recorded the cents portions of those checks. The table below lists those cents portions categorized according to the indicated values. Use a 0.05 significance level to test the claim that the four categories are equally likely. The person expected that many checks for whole dollar amounts would result in a disproportionately high frequency for the first category, but do the results support that expectation?

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? TABLE Did the Subject Actually Lie? No (Did Not Lie) Yes (Lied) Polygraph test indicated that the subject lied. 7 41 Polygraph test indicated that the subject did not lie. 18 11 Determine the test statistic. X2 = The P-value is
