A tourist company did a survey to determine if more New Yorkers or more Californians recognize a certain type of giraffe. Of the 554 New Yorkers surveyed, 177 knew the type of giraffe while 198 out 622 Californians knew the type of giraffe. At the 0.01 significance level, test the claim that the recognition rates of a certain type of giraffe are the same in both states. What are the correct hypotheses?

An online poll​ asked: "Do you believe the Loch Ness monster​ exists?" Among 21,523 responses, 61% were​ "yes." Use a 0.01 significance level to test the claim that most people believe that the Loch Ness monster exists. How is the conclusion affected by the fact that Internet users who saw the question could decide whether to​ respond?

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 294 people over the age of​ 55, 78 dream in black and​ white, and among 291 people under the age of​ 25, 10 dream in black and white. Use a 0.01 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Complete parts​ (a) through​ (c) below indentify test statistic p value= the 90% confidence interval is

Christine, a researcher in psychology and biobehavioral health, believes that city residents and residents of rural areas differ in how appealing they find owning a cat. A random sample of 109 people who live in San Antonio were surveyed and 59 identified themselves as a "cat person." A random sample of 108 people who live in the surrounding rural area were selected and 72 identified themselves as a "cat person." Conduct an appropriate hypothesis test at the a = 0.1 significance level to test Christine's claim. Round answers to 4 decimal places where appropriate. a. State the null and alternative hypotheses. Ho: p. H₁: p. b. What is the appropriate distribution to use for the hypothesis test? Z (Normal) c. Find the test statistic. Test Statistic: -1.9593 X d. Determine the P-value: op. P-value: 0.0501 X O p.

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 285 people over the age of 55, 76 dream in black and white, and among 287 people under the age of 25, 10 dream in black and white. Use a 0.01 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Test the claim using a hypothesis test. Consider the first sample to be the sample of people over the age of 55 and the second sample to be the sample of people under the age of 25. What are the null and alternative hypotheses for the hypothesis test? O A. Ho: P1 = P2 H: P1> P2 O B. Ho: P1 = P2 OC.

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?   LOADING... Click the icon to view the table. Determine the null and alternative hypotheses.     A. H0​: Polygraph testing is accurate. H1​: Polygraph testing is not accurate.   B. H0​: Polygraph testing is not accurate. H1​: Polygraph testing is accurate.   C. H0​: Whether a subject lies is independent of the polygraph test indication. H1​: Whether a subject lies is not independent of the polygraph test indication. Your answer is correct.   D. H0​: Whether a subject lies is not independent of the polygraph…

Past studies have indicated that the percentage of smokers was estimated to be about 34%. Given the new smoking cessation programs that have been implemented, you now believe that the percentage of smokers has reduced. You randomly surveyed 1807 people and found that 574 smoke. Use a 0.05 significance level to test the claim that the percentage of smokers has reduced. a) Identify the null and alternative hypotheses? Но: ? H1: ? v b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? O left-tailed O right-tailed O two-tailed c) Identify the appropriate significance level. d) Calculate your test statistic. Write the result below, and be sure to round your final answer to two decimal places. e) Calculate your p-value. Write the result below, and be sure to round your final answer to four decimal places. f) Do you reject the null hypothesis? O We reject the null hypothesis, since the p-value is less than the significance level. O We reject the null hypothesis,…
